600/800mm - 24" (8/12/15): at 225x; an extremely low surface brightness halo, perhaps 1' diameter, was obvious in excellent transparency and seeing, though I couldn't verify it was brighter along the rim (ring structure).

24" (7/14/15): this Ring galaxy appeared fairly faint to moderately bright, fairly small, round, 30" diameter. There appeared to be an extremely faint halo (this is an outer ring), but no ring structure. Jimi thought 1 or 2 arcs in the ring were visible. A mag 15.9 star lies 1.2' SW. MCG +08-29-040 (V = 15.5) lies 5.9' NW and MCG +08-29-042 (V = 15.6) is 7' N. Both of these are thin edge-ons. Also nearby are UGC 10150 15' SW and the MCG +08-29-043/-044 pair is ~13' NE.
