Also known as the Running Man Nebula
Emission & reflection nebula in Orion
7th magnitude
40’x25’ apparent size
The Trapezium
Tight open cluster at the heart of the Orion Nebula
Four young stars formed from the Orion Nebula
5th Magnitude
NGC 2295
Spiral galaxy in Canis Majoris
13.5th magnitude
2.1’x0.6’ apparent size
Rupes Altai
An escarpment in the lunar surface
Located in the south east quadrant of the Moon’s near side (of course)
Approximately 427km long
2021 Messier 38
Open star cluster in Auriga
Also catalogued as NGC1912
~3480ly away
Barnard 226
Dark nebula in Auriga
Near the open cluster M36
Simeis 147
Supernova Remnant in Taurus
Huge but dim object: 200’
apparent size
Supernova thought to have occurred 99,000 years ago
Crater Cleomedes
Lunar impact crater
126km in diameter
Just north of Mare Crisis
  M38 Andrew Brown 2019-03

Messier 79
Globular cluster in Lepus
60,000 ly away from earth
8.56 apparent magnitude
8.7’ angular size

AKA the Horsehead Nebula
Emission nebula in Orion
7.3 apparent magnitude

Spiral galaxy in Taurus
Sits in the midst of the Pleiades
17.8 apparent magnitude

Rima Hyginus
A lunar rille that bisects crater Hyginus
220km in length
Deformed by various crater impacts


M1 - The Crab Nebula
Supernova remnant in Taurus
8.4 Magnitude
Visible in small telescopes, but details reserved for larger instruments

The Rosette Nebula
Cataloged as Caldwell 49
Contains several objects: NGC2237, 2238, 2239, 2244, 2246
Clusters easy in small scope, nebulosity might require a larger instrument at low magnification

Sharpless 2-301
Emission nebula in Canis Majoris
Approximately 9’ x 8’ in angular size
Best viewed with a large instrument, but you may need to use a UHC filter to draw it from the background sky

Alpine Valley Rille
Located on the floor of Valis Alpes
Rille in the centre of the valley
140km in length, but never more than 1km wide
At least 150x magnification required to see
