George Johnstone Stoney or Bindon Stoney, LdR's assistants, discovered NGC 4109 on 21 Apr 1851. During an observation of NGC 4111, it was noted "the first [NGC 4109] is vF and 6' ssp the second NGC 4111], which is vB and mE. A double star is 5' nf, whose smaller component is blue." Although mentioned in the 1861 publication, John Herschel did not include this galaxy in the GC so Dreyer added it to the GC Supplement (GCS 5618).

300/350mm - 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.

600/800mm - 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.
