The Oval’s Southeastern End
NGC 4921 is the third-brightest galaxy in the central Coma Cluster after NGC 4889 and 4874, the two huge ellipticals at the cluster’s center. Large and amorphous, NGC 4921 is immediately recognizable as a face-on spiral. Slightly elongated NGC 4923 lies only 2.6′ south-southeast of NGC 4921 while another bright spiral, elongated and relatively large NGC 4911 (shown above), is 9′ southwest of NGC 4921. Tougher NGC 4919 lurks almost midway between NGCs 4923 and 4911, and slightly southeast of the line connecting them. I was able to detect a few photons from 15th-magnitude PGC 44864 because it lies 2′ west-northwest of NGC 4919 directly along a line to a 12th-magnitude star 6′ farther west-northwest. The task was not made any easier by the need to repeatedly refind my landmark, shy NGC 4919.
The Coma Cluster includes a few fine spiral galaxies as well as a huge number of ellipticals. North is to the upper left in this extraordinary photograph of NGC 4911 from the Hubble Space Telescope.
North of NGC 4911
An easy star-hop north-northwest from bright NGC 4911 leads to a band of seven galaxies. NGC 4906 is small and faint, but not difficult. Small IC 4042 is obvious, but I can only occasionally see IC 4041 in the sweet spot of my averted vision. While I was hunting IC 4041 at 229×, a line of three galaxies appeared along the eastern edge of the field of view. IC 4051 is relatively large and displays a nucleus. NGC 4908 is fairly small, and more concentrated than rated the surrounding IC ng

Coma Through 12.5 Inches
It was with great pleasure that I accepted Alan Whitman’s invitation to contribute a sketch of the Coma Cluster through my 12.5-inch Dobsonian reflector. I soon realized that capturing what turned out to be 33 objects in a single field of view was a challenge like none that I had ever met before. Instead of sketching the eyepiece view directly, I combined observations over multiple nights at magnifications from 93× to 263×. Guy Mackie observes the deep sky from southern British Columbia.
