imaged NGC 4111 and friends (Halifax)

BGO also imaged NGC 4111 (and neighbours) for me. A lovely edge-on galaxy in Canes Venatici. One of the RASC Finest NGCs.

RASC Finest galaxy NGC 4111 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

North of the canted spiral are four faint small round fuzzies: LEDA 2214969, LEDA 2214632, LEDA 2215310, and LEDA 2214631.

To the west is the large, very faint, and disturbed galaxy MCG 7-25-20. It's actually just over the border, in Ursa Major.

South-west of 4111, near the bottom-right corner, is the faint oval of MCG 7-25-22. Also in UMa.

Closer to the main target is NGC 4109 with its bright centre. Immediately below 4109 is a tiny oval: LEDA 2210517. To the east of 4109, further away, is a brighter oval: LEDA 2210701. Further still, but barely detectable, is the larger smudge of MCG 7-25-25.

Due east of the core of 4111 in a small faint oval. Is LEDA 2212301 a companion?

North-east of the galaxy is the double star HD 105288. Actually, a triple. Oddly, the C star appears to correspond to the core of NGC 4111.

Beyond the double are two more galaxies. Large, bright NGC 4117 and small, faint NGC 4118.
