EDITORIAL
Meetings of our Council are seldom reported in these
pages - not that they are unimportant in the health and
smooth running of the Centre, but really because the Centre
is smooth running. The Officers present regular reports to
the Council, any difficulties are ironed out, the future
program of meetings is discussed, and after any special
items and any other business the members of Council are
treated to coffee and eats by the President's wife.
In the latter respect we have been singularly fortu­
nate for many years and the present is no exception. We
sometimes wonder how long the President can afford to feed
us on the scale to which tradition has accustomed us.
Maybe that is why Dr. Higgs has taken the opportunity to
go to Penticton for a year!
Actually, we understand that his principal task there
will be to tie-in the radio telescopes to computers for the
rapid assimilation and processing of data - work that he
has already performed with distinction at Algonquin - but
his many papers indicate that he is very much an astronomer
as well as a computer expert, interested in far more than
merely getting the right numbers to the right places in the
computer, as his Presidential Address made very clear.
Our thanks to Dr, and Mrs. Higgs - heck! let's say
Lloyd and Kathy - for all they have done for us.
The Presidential vacancy will be filled by none other
than Mr. Hans Klinkenberg, now First Vice-President, whose
sense of humour has already been well tried and proven by
participation in one of our famous graze expeditions,
Welcome, Hans! We just hope the year will not be too
tough on your wife.OBSERVERS GROUP MEETING - MARCH 3
Cathy Hall
Mr. Tothill chaired an exceedingly informative meeting.
Sixty-three persons were present, 76% members, with 73% of
members and 27% of non-members possessing scopes.
Dr. Lossing related more news of the oscillator for the
16", followed by Ed ter Heijden's explanation of the building
of his Polaroid-turned-sky camera.
Another quasar, 3C 273, was introduced by Ken Hewitt-
White, who also talked on coming planetary configurations,
the meteor data for C.P. Olivier's 5th hourly rate catalog,
the Virginid shower, and the proximity of Jupiter and M8
about July.
Following this, Walter Turner gave a talk on the calcu­
lation of the angular diameter of the moon.
Data was presented by Rolf Meier on the strange apparent
orbit of Toro, on the Pioneer 10 mission, and the unfortunat­
ely cancelled grand tour of the planets, along with info on
the positions of Pluto and Mercury. He showed slides of a
planetary configuration, gradually "zooming in", and some by
Rob Dick of Venus and Mars (evidently the red planet),
Jon Buchanan presented the main talk of the evening, a
rather interesting one complete with slides on the possibili­
ties of life in the solar system (not necessarily intelli­
gent.*) This consisted of a general analysis of life sys­
tems and an examination of conditions on each of the planets
from a mainly chemical point of view.
In closing, some colour slides of several objects were
shown by Art Fraser.

DR. HIGGS' PRESIDENTIAL ADDRESS
On March 22 Dr. Lloyd Higgs spoke to the Centre on
"Atoms and Molecules in Gaseous Nebulae" discovered through
radio frequency spectroscopy, with special emphasis on the
Algonquin Radio Observatory's studies of the Orion nebula
M 42. We wish him and his family a happy year in Penticton.LUNAR
Barry Matthews
With fair weather coming on and more and more observers
getting out and viewing I have set up a program for myself
to keep 12 lunar features under surveillance from sunrise to
sunset. This program is not photographic, but I would cer­
tainly appreciate any copies of photos for my own personal
record. How else do you record this our nearest neighbour?
By drawing the features with pen and pencil. (If anyone
wants a copy of an earlier paper on drawing the lunar fea­
tures see me after the next meeting). The features I will
be keeping track of are as follows:
1.
2.
3.
4.

Langrenus
Posidonius
Archimedes
Copernicus
Tycho
Gassendi
Sinus Iridum
Ariadaeus Rille
Hyginus Rille
Eratosthenes
Mount Piton
Mount Pico
A year ago when I was carrying out a similar program I
found I was getting bad results due to perspective. I think
I have a solution; by using a simple grid and a number of
dots you can keep these features in the right place. I will
have copies of the grids I have made up for the preceeding
12 features at the meeting and would like a couple of volun­
teers to give them an unbiased trial. This is an easy way
to get around the moon and provide a training ground for
other things.
We hear from the I.U.A.A. lunar co-ordinator that
Ottawa was not the only place clouded out for the Jan 30
lunar eclipse. Such exotic places as Greensboro N.C.,
Chino Cal., Louisiana, Brown Wood Texas, and Wadsworth Ohio
all were the recipients of Murphy's fickle finger.

DR. ALAN S. WRIGHT'S ADDRESS - FEB 17
A number of pairs of galaxies exist with "tails"
extending from one or the other, not necessarily connectingthem. Dr. Wright described an interesting computer simula­
tion which had shown that if a disturbing mass or galaxy
passed around a galaxy on a parabolic orbit in the same
sense as the rotation of the stars within the galaxy, then
a bridge of stars would in many cases be drawn out after
the interaction, usually on the opposite side to the
retreating mass.

A PROJECT FOR VARIABLE STAR OBSERVERS
Ken Hewitt-White
Written up in the RASC Journal for December 1971 is an
article concerning a peculiar variable star - XZ Cygni.
This is a short-period RR Lyrae type star that is undergoing
some strange changes in behaviour. The star normally ranges
from 8 .7 to 10.4 magnitude with a period of 1 1 . 2 hours, the
actual climb from min to max taking only about 60 minutes.
However in recent years the variable's observed maxima have
advanced ahead of the predicted values with an increasing
amount with each period observed. The last observed max
was nearly six hours ahead of the predicted time. Needless
to say, this is an intriguing phenomenon. The AAVSO would
like observations of this star to help correlate with recent
findings. The roller-coaster action of this variable along
with the advances of the phase position should make it a
fascinating object to study.
In the morning of March 20 I found this star quite
easily using guide stars near NGC 6826. It is a bright
field just west of the Milky Way. In a field of 1 degree,
XZ is beautifully framed by a triangle of bright stars making
it an easy target to zero in on, Our first estimates that
night indicated that XZ was at minimum but we saw it starting
to rise before we closed up for the night.
XZ Cygni has special significance for a few of us in
particular. One of the main problems in interpreting light
curves of OJ 287 ( and now 3C 273) has been the difficulty
in separating source fluctuations from fluctuations in
atmospheric scintillation and observer equation. With
XZ
Cygni, we have a source of known range and time (for max-min
segment). Observations of the variable should help reduce
some of the unknowns involved with the quasars - scintilla­
tion for one, Some of the other parameters are more diffi­
cult to quantify but Ed ter Heijden's Fourier analysis pro­
gram is helping us out there.XZ 's full range is visible in a six-inch. 16-inch
quas-hunters and variable star observers can now work to
help each other and together can give the AAVSO a boost too.
For those interested in starting a program on XZ Cygni,
there are finder charts and other data available on pp. 307-
309 of the above-mentioned issue of the Journal.

DEEP SKY
Robert Dick
By the time Astronotes is distributed the time will
have come when those heat freaks of winter come out of the
woodwork, and turn their heads from those snow-banks back
to the sky. Their eyes will be warmed by the constellations
Cancer and Leo (or if you are in the city, just the brighter
stars of Leo). This corresponds to 11 hours of Right
Ascension,
Trailing Leo is what is popularly called the Coma-
Virgo group of galaxies, dancing between the pan of the Big
Dipper and the northern reaches of Hydra and passing through
the constellations of Coma Berenices and Virgo.
But before we reach this maze of mystery, Coma-Virgo,
there are a few objects in Leo itself which are no mean
task to find, especially in large scopes. These are all
galaxies and pictures will be shown at the meeting, hopefully.
The easiest to find is NGC 2903, fairly dim in small
scopes. To find it you just sink down from Lambda Leo
about 11⁄2° . The others, though some a re a mite brighter,
are more difficult to locate. Two of these objects were
listed by Charles Messier and are called M95 and M96. Like
the rest they may require an equatorially-mounted scope.
To find them start at Alpha Leo (Regulus) and move east
about 10°. This will give you M96. From there move south
about 0.2° (1 2 ' of arc) then west 1°. This is M95.
The next group is

Start at Theta Leo then east 0.5° then south 2° to a bright
star Leo 73. There is another star about 0.5° south of it.Aim your scope in the centre of the two then drift east with
low magnification 0,8° to 1.0°. These two galaxies are M66
(east) and M65 (west). From M66 go north 0.6°; this last
object is NGC 3628.

-Ed.UPON BEING A NEW MEMBER
Isabella Darinzanco
A notorious Van whisked by the door, I flashed the
porch light on and off. Sure enough it was part of the
executive and his crew, arriving "on schedule", to pick
me up for North Mountain.
Armed with my binoculars, cub star finder and several
little books that I had just received in the mail from
Barry Matthews, I was ready for my first review lesson or
whatever.
I immediately was instructed about the geography of
North Mountain’s illustrious bumps and flyways, as we raced
to the site.
"22.5"
"22.5"
"22.6"
"22. 6 " - and so on. What was this? Were we going to
blast off? The driver was giving countdowns to a co-driver
hidden somewhere in the rear, who was recording something or
other. No, it was only a mileage count.
Awaiting us, at the Site, were Bob McCallum, with
Walter Turner who was digging his car into safety, and Mrs.
Knapp with her new telescope.
It was then that I learned the real truth - Executives
don't have keys! Also the Van was not going to return
until dawn. I hadn't given a particular hour of return to
my husband, who already viewed me strangely for wanting to
study the constellations and related factors, rising and
setting, for several hours at a time. Would he be prepared
for this?
The heavens were magnificent, on March 10th, at North
Mountain. This was the problem: there were such a great
number of celestial objects that I had difficulty picking
out the few miserly constellations, known to me, that were
so evident near my own home. Immediately I knew that it
would be better to remain silent, than to reveal this
terrible truth.
Following these great revelations, I was to receive
another instructive lesson: how to find a telephone booth
that stays up all night, near North Mountain.After several articles of groceries came back from
Osgoode in the Van, someone decided to use the phone that
they had found there also.
Lesson 3 - six people in a Van, studying the ceiling
while Orion set in the west.
Lesson 4 - "It’s one of us!" shouts K.H-W., hiding
under his peaked cap.
Peering through the rear Van window, I viewed a car
slowly approaching on the observatory road, with only yellow
parking lights on.
"Oh, no! - not Karl Poirier!
cringing.
Is it Karl?" K.H-W. says,
"No, it's Rob Dick!"
Rob to the rescue, with Cathy Hall, Lindsey Davis,
and doughnuts. Was this ever going to involve the heavenly
objects at all?
Yes. K.H-W. set up the 16" as soon as he could get
his hands near it, and the show began. A beautiful whirl­
pool galaxy and its partner, similar to our own; several
other galaxies, edge on; globular clusters;- it is at these
times that I am not quite sure if I am seeing what I am
supposed to see. Deciding to vocalize what I saw (when
asked) was a great benefit. I did see the correct object
as it was. But I still hadn't found out if the equator
was at the right place or not.
Soon I discovered, that Walter Turner was digging his
car out of its burial place and returning to Ottawa. I felt
that this was the wisest thing to do also, if possible.
Regretting leaving Pluto unseen and all the other
wonders, I gathered my bag of frugal beginner's information
together, fastened my safety belt, and was set for the
flight to Highway 3 1 .
Maybe, next time, I will be allowed to stay up all
night and find out if I do know where the equator is or not!
It was fun and I appreciated the good intentions. I am
looking forward to the basic astronomy course Apr 14 and 21.Thank you all for finally noticing me, and for your
aid to the beginner.
Bye for now - an anonymous member,
Now known as Isabella.

PLANETARY EVENTS IN APRIL
Rolf Meier
The sky highlight of this month is figured to be a
configuration which lights the sky high above the western
horizon at sunset. I have scheduled the participants to be
Mars, Venus, and Saturn, and the moon will also wander
among these planets between the 14th and 17th. The scene
will be enhanced by the Hyades and especially the Pleiades
who were kind enough to be with Venus and assist her seven
times. The star of the show will be Aldebaran, and Saturn
will be in its vicinity for some time.
On the 16th, Venus will pass very close to the moon
and an occultation will occur, but I have not been able to
find out whether or not it will be seen in Ottawa (No.-Ed.)
though a close approach is eminently imminent (about 2 5 '
from northern cusp around 21:15 EST. -Ed.) and I hope the
prediction isn't a lot of Bull, because otherwise the only
way we'd stop watching for it is if someone 'tore us' from
our scopes. (Ouch! -Ed.)
I expect the configuration will be much photographed,
and hopefully we will receive some exposure to your pic­
tures at future meetings. Don't bring your bad slides,
because we don't want to see a bad pigment of your film's
illumination, even though you may think we're crazy enough
to be fooled. Make sure the camera is well supported when
the picture is taken. Exposures should be about 20 seconds
at the most for a stationary camera before trailing occurs,
and in that time stars down to 6th magnitude will be recor­
ded on High Speed Ektachrome at f/2. To assist in photo­
graphy I hope to have copies of a map I have made of the
area ready for the April meeting.
Don't look now but Uranus will be in full view when it
comes to opposition on the 5th. Its motion can be followed
by any scope, or even binoculars, since it is unmistakablygreenish-blue.
Did you know Juno is in opposition on the 1 st? No
fooling, but it will be faint, at 10th magnitude. Its posi­
tion will be RA 12h 53m, Dec +2° 2 . 6 '; for more information
consult the BAA Handbook,
This double opposition will be followed by a double
elongation, Venus on the 7th (46°) in the evening sky, and
Mercury on the 28th (27°) in the morning sky. That 27° for
Mercury is a bit deceiving, since it will be scarcely 10°
above the horizon at sunrise due to the angle at which the
ecliptic meets the horizon in that part of the sky. I have
been supplied with a computer printout of Mercury's position
for the next several months through the courtesy of Ed ter
Heijden, and I would be glad to share this information with
anyone who gives me a call.
Jupiter will probably be as good in April as the rest of
the year, so when you are searching that rich Sagittarius
area for some galactic clusters and nebulae in the hopes that
a sight of the summer Milky Way will melt the ice on your
observatory floor, just skip over and look at the king of the
planets and chief of the gods. The background stars will be
plentiful, and at least five Messier objects will be within
5 degrees, making this a great area to observe in.

REFLECTORS - PART 6
Allen Miller
It has been brought to my attention that these articles
that I have been writing are still above the heads of begin­
ning mirror makers. This is unfortunate but I think it
should be noted that all I am writing is a brief summary of
the steps involved to start and complete a mirror. There
are mountains of information written for reflectors and
somehow I don't think Ed. would enjoy typing 4 million pages
of Astronotes. Finally, before I continue with figuring
and testing, if you find these articles are involved ask my
person for explanations.
In the last article you read, I revealed that there are
several ways to obtain a parabola from differing shapes
unlike a sphere, They all involve applying pressure of the
pitch lap or laps if you wish to try several types.
To parabolize a six-inch, long focus (f/7 to f/9), thebest pitch lap is a full-sized one with the grooves between
the facets widening to about an extra quarter inch at the
edge. The mirror should then be placed on top of the lap
and pushed in a large, full, zig-zag stroke so that the
centre just reaches to about half an inch from the edge of
the lap. Polish for about four minutes then test. This
way any abnormalities can be corrected before they get out
of hand. Usually the edge does not turn enough so to remedy
this, reverse the mirror and lap keeping the stroke the same
as before. Polish for a minute and then test. Before any
testing is done let the mirror cool for fifteen minutes and
during the final stages of figuring an hour may be necess­
ary.
Testing
If your Foucault tester has a micrometer or else a
calibrated bolt thread (such as that in Sam Brown's book)
to move the knife-edge, there is a simple formula you must
have to figure your mirror accurately:
d = r2/R
where d = deviation of the knife-edge from
its position for the centre zone,
r = radius of the zone you wish to
calculate d for,
R = radius of curvature of your mirror.
If you are using inches the result would be a range
from 0 to 0 .250 inches for an 8" f/4 .
To measure a zone the best way is to make a mask of
cardboard with slits located at known positions around the
centre. Three necessary zones are the centre (zero), 70%
zone, and the edge (95 to 100% of the radius).
This mask
is placed in front on the face of the mirror so that the
slits are parallel to the light source slit.Now move the knife-edge back and forth until the centre
goes grey all at once when the edge is cut in, hark and call
this position zero. Now move the edge back until the 70%
zone slits appear to go grey in unison. Once this position
is marked move further back and measure the edge zone. To
compare your mirror with the ideal parabola use a graph with
d on the y-axis and r on the x-axis. An undercorrected sur­
face will lie below the r2/R curve, but any positive trends
on the curve indicate over-correction. It should not be
necessary to mention that the smoother you keep your curve
the easier in the long run it will be to figure a good
mirror.

PLANETARY PHOTOGRAPHY - 2: OPTICAL SYSTEMS
Rolf Meier
The following are abbreviations used in this articles
d = angular diameter of celestial object (seconds of arc).
D = diameter of objective,
f = focal length of eyepiece,
f' = focal length of camera lens.
F = focal length of objective.
M = magnification.
P = power of telescope.
EFL = effective focal length.
The size of an image produced by any lens or mirror
depends on the focal length of that particular item, the
longer the focal length the larger the image. This is an
important factor to consider in lunar and planetary photo­
graphy. The actual formula which gives the size in inches
of an image is; d x EFL/206000. For planets this gives a
rather small value with short focal lengths because of their
small angular diameter, and small features on the moon will
also have small images, and will consequently not be recor­
ded on film. This difficulty arises from the fact that
films are simply not capable of recording infinitely small
detail over a certain surface area.
This leaves us with two alternatives. Either we can
build enormous reflectors and refractors with very long
focal lengths, or use conventional focal ratios and use some
sort of optical amplifying system to enlarge the small image
produced by the primary objective. The latter choice will
be found to be the most convenient, so it is the one which
will be discussed here.The most common enlarger is the eyepiece of the tele­
scope. Just imagine that instead of your eye, the camera
is placed at the exit pupil. Now the lens of the camera
will focus the light leaving the eyepiece, and the image
will fall on the plane of the film instead of the retina.
It must be remembered that the camera is to be focussed to
infinity, and that the eyepiece be focussed as well as poss­
ible for the corrected eye, otherwise the image will be
blurred. Almost any camera can be used this way, and it is
with this system that I have achieved the best success, as
far as detail is concerned, despite various difficulties.
For example, without a reflex, there is really no way to be
sure of the focus, or ev en if the object is in the field.
The following is a diagram and a formula for calculating
effective focal lengths
Fig.

EFL = P x f'
P = F/f
The eyepiece of the telescope is also often used for
projecting an enlarged image onto the film. If the eyepiece
is racked out slightly, it will be out of focus to the eye,
but an enlarged real image will exist somewhere beyond the
eyepiece. This is familiar to solar observers, who find
this most convenient for observing the sun. Be sure to use
the best eyepiece available, preferably an orthoscopic.
The camera lens must be removed from the camera. Focussing
is achieved by replacing the film with a ground glass view­
ing screen. With a single lens reflex, this presents no
problem at all, so it is no wonder that this system is most
efficient with this type of camera. Opposite is a diagram
showing how it works, a formula for calculati ng the focal
length, and a table for common focal-length ey epieces:Fig.

A procedure similar to eyepiece projection is negative
lens or Barlow projection. The setup for photography is the
same as for eyepiece projection, but instead of there being
a primary image which is projected, the Barlow intercepts the
light beam and in effect lengthens the focal length. Read
Rob Dick's article in the December '71 issue of Astronotes
for some very useful information on Barlows.
For reflectors of very short focal ratio the image is
often enlarged by a secondary mirror, which is either convex
or concave. The result will be a Cassegrain or Gregorianreflector respectively. The image will be so large that it
may not be necessary to enlarge it further by projection,
so the film can be placed directly at the focus. For some
words of wisdom concerning the construction of compound
reflectors, Allen Miller is the person to see.
bear in mind that it will not always be necessary to
use a large image for lunar pictures. For eclipse pictures,
or for capturing earthshine, short focal lengths and small
focal ratios are best for getting the whole disc in and for
decreasing exposure time. For pictures of the planets'
satellites, a short focal length may also be better to
reduce driving error in the longer exposures needed.
The item to be dealt with in next month's article is
exposure. It was necessary to discuss optics first because
we must know how to calculate effective focal ratios, given
by the formulas EFL/D. Focal ratio is the factor which
decides how much detail we can ultimately resolve from an
image without getting a distorted blob. It is also the
factor which decides exposure time for extended objects
such as the moon and planets. Our effective focal length
must be chosen by compromise so that we achieve favourable
results.

A BEGINNER'S COURSE IN OBSERVING THE STARS
Kenneth H-White
Beginning April 1.4, the Observers Group will be spon­
soring a series of three observational meetings designed
specifically for the beginning star watcher. The influx of
new members into the Observers Group along with an ever­
growing interest on the part of nearly everyone to learn
more about the stars has prompted us to try our hand at the
teaching game, Thus our New Member co-ordinator, Barry
Matthews, along with Messrs K. Hewitt-White and R. Dick
have selected a series of topics to discuss with newcomers
to astronomy at this new series of meetings. The meetings
will take place at the usual room (Geophysical Library,
Observatory) at the slightly earlier time of 8:00 pm on
April 14 and 21. On the 22nd of April, a practical session
will be held at North Mountain using a variety of telescopes
as well as the 16-inch. Anyone can take part, members and
non-members alike. If you are new to astronomy or need a
refresher course in observational basics, then these infor­
mal get-togethers are for you. A rough itinerary showing
our selected program follows.14 April, 8:00 pm "All about Telescopes".

of Stan Mott and the library.

Barry Matthews
Once again it is time for fable and fact. This time
it is fact. A new Periodical has found its way to the
library shelves as if by magic. Our honoured librarian
Stan Mott appears to be able to sense a real winner even
before it has reached general distribution, I am speaking
this month of Astronomy & Space, edited by Patrick Moore
with a list of contributors like the who's who of the astro­
nomical world.
Astronomy & Space rises above the average periodical
with superb reproductions on fine grade paper with articles
by first class authors. With Patrick Moore at the editorial
helm the reader is led through the pages of varying com­
plexity in Moore's easy and informative style. Our Library
has now received the first three issues and readers are
urged to look these issues up for the next time they are
clouded out.

EQUIPMENT LIBRARY
Barry Matthews
The co-ordinator for New Members is very pleased to
report that Mark Leenders, a new member, was the first to
take advantage of the scope in the "equipment library".
It now appears that we will have some other pieces of
equipment for the library; any additional pieces of equip­
ment that you have around and would like to see used please
contact me or Ken Hewitt-White. There is now a waiting
list for my 3 . 5 " reflector.

Tom Tothill
"We've got you in the Super Sixteen. Gome to the
window and smile. The boys want to get a picture."
Red Schlossing was startled by Ravery's voice, coming
in loud and clear. Gosh! was he around already? He'd only
just finished the Herculean task of re-making that damned
couch.
But by the time Rubber Duck and Golf Dreiver had
fiddled, faddled, fuddled and duddled his face was one big
ache. They got him just before he set.
The flight plan called, for 16 orbits of "rest" while
the cryogenics radiated down to a usable level. Schlossing
soon found that the trouble with sleeping in orbit is that
you wake up with a start, thinking you are falling, and
find that you are. So he spent as much time as possible
talking to the Communicator, Pen Kerrins (Grady Grunt having
gone off duty for an evening of Mobius strip manipulation)
about the System - that is, the electronics. He had the
manual on board, of course, on microfilm, but no one who has
ever read a manual written by technicians for technicians
ever wants to repeat the experience. Kerrins kept working
the conversation around to the coffee machine, but Schlossing
kept him rigidly to the point and soon felt that he knew
what all the circuits did and was pretty confident that he
could fix them if need be. For when it came to electronics,
Schlossing was no schlouch.
Odd, he reflected during a period on the back side,
that Kerrins and Grunt should be teamed up in this mission.
They had once been in the restaurant business together, but
couldn't make it pay. He bet they were often nostalgic for
the good old days, slinging hash together down at the old
"Tuck fer a Buck", When inflation hit, they found there
wasn't room to extend the neon flasher to "Tuck fer a Buck
'n a Quarter". So they folded.
Nowadays about all they fried was transistors.
