Description:
Gx, 12,7magv, 1,9x1,1’, UMa. Closely attached to a triangle of 12-13mag stars. At 
244x this high surface brightness object extends 1,2x0,7’ N-S. I could see a faint 
and small core cloud but no sign of a stellar nucleus. NGC3415 is a very easy 
target even though it’s brightness is only 12,7.
