Description:
At the edge of direct visibility, very tiny galaxy. The shape is very difficult to see because of the low surface brightness. It isn't smooth, and it looks like it has TWO stellar cores. I suspect a little tentacle on the Northern side. At 71x it looks like a defocused star. At 250x it looks better but it's still best to view with averted vision. This is a fine example that one must always believe his eyes: I never check objects beforehand but decide on what to observe on the spot, based on my list of previously unobserved objects. I've checked later on astrophotographs and it really has a dual stellar core - probably one of them is a foreground star.
