Last Tuesday night Jim Chandler and I tried this pair on a night of fair transparency and below average seeing.
UGC 816 was brighter than UGC 813 and with the 12MM TMB Supermono at 407X during moments of good seeing the faint bridge between UGC 816 to UGC 813 would pop in. The bridge to my eye would not quiet go all the way to UGC 813 but faded out 3/4 of the way to it. I could not hold this with AV it would only momentarily pop in and out of view with the seeing.
The dwarf galaxy with the 12MM TMB was direct vision and in moments of good seeing would extend looking like a 1/4 facing spiral with a brighter core. I was surprised at how dim the star it was by was on this night. You have to look in just the right spot to see the dwarf as it is small and dose not jump out at you in the crowded star field and at low power looks like a fuzzy star with a spike on one side.
