Barnard 86
 
 is a dark nebula (a "Bok globule") also located in the  constellation of Sagittarius near NGC6520, which was possibly this open cluster.

Abell 70

is a planetary nebula in the constellation of Aquila, and a challenging target at a mere 42" diameter.

Montes Harbinger
 
is a cluster of mountains to be found on the north-wetsren border of Mare Imbrium and covers about 900 sq km.

I still encourage more people submit reports than did this past month -- I encourage everyone to participate, not just imagers! You can submit reports by way of images, sketches, or even without any imagery, you can come up and give a verbal report that perhaps includes the conditions you made your observations under, and the details of the equipment you used -- and of course a description of the object as you observed it! Be sure to send them to me for inclusion in the next meeting at meetingchair[at]ottawa.rasc.ca

NGC 6886
 
NGC 6886 is a planetary nebula with a size of only about 0.3 X 0.45 light-year, located some 7,000 to 11,000 light-years away from Earth in the northern constellation of Sagitta.

Abell Galaxy Cluster 2151

also known as the Hercules Cluster (and not to be confused with the globular cluster M13)  comprises about 200 galaxies some 500 million light-years distant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies.

Rupes Kelvin & Promontorium Kelvin
 
Rupes Kelvin is a 78 km long escarpment near Promontorium Kelvin, a headland  located in the southeast of the Mare Humorum.

Videos added for March and April 2019 Meetings.

In March, Sharon Odell provided an update on the work and prospects of the RASC Ottawa Diminion Observatory Subcomittee's work to preserve and conserve the original observatory, and also presented a video testimony to "Courage and Passion: Canadian Womern in Natural Sciences" during the break. Following that, astrophysicist Dr Matt Caplan of the McGill Space Institute took the audience into the nasty, throbbing nuclear waffles pasta at hearts of neutron stars that yield gold (and other, more useful stuff), and highlighted the "remarkable agreement between theory and more theory" underpinning these discoveries. See the video here.

  

Following, at the April meeting, Dr Janet Tulloch of Carleton University continued to fascinate with the presentation started back at the February meeting on the "Outstanding Standing Stones" eatsblished in neolithic Orkneys and especially their solsticial alignments, and that can be found here.

M101
(NGC 5457)

a.k.a the Piwheel Galaxy, is a face-on "grand design" spiral galaxy distanced 21 million light-years (six megaparsecs)[3] away from Earth in the constellation Ursa Major.

NGC 4361
 
NGC 4361 is a planetary nebula in the constellation of Corvus.

Hickson Compact Group 50

Hickson 50 is considered the most difficult of the Hickson galaxy groups to observe. It is estimated by some to be 2 billion light-years in distance, based on red shift measurements.

Lambert R
 "Gohst crater" Lambert R
Just to the south of Lambert's ramparts is the lava-covered rim of Lambert R, a crater that is almost completely covered by the mare. The diameter of this ghost crater is larger than Lambert, but it is difficult to spot except when the Sun is at a very low angle, casting long shadows.
