Steve's Notes
=====
NGC 4109
24" (5/30/16): fairly faint, fairly small, roundish, 20" diameter, broad weak concentration. Forms a close pair with LEDA 2210701 just 40" to the east. A mag 13.5 star lies 1' NNW. NGC 4109 is situated 4.7' SSE and UGC 7094 is 7.7' SW.
LEDA 2210701 appeared extremely faint and small, ~6" diameter. Once acquired, I could hold it nearly 50% of the time, despite a very low SDSS magnitude (V ~16.0). The redshift of z = .086 implies a light-travel time of 1.1 billion years!
UGC 7094 is very faint, edge-on 4:1 SW-NE, 1.0'x0.25', very low surface brightness with no noticeable concentration.
13.1" (4/12/86): very faint, small, round. Forms a pair with NGC 4111 5.0' NNE. NGC 4117 lies 9' NE. Located on the Ursa Major-Canes Venatici border.
