Description: at 271x, small galaxy, faint, seen 
continuously with averted vision, observed from 
80 to 426x, showing an arrow-head shape (pointing 
SW at about PA210°); estimated size of 1.0'x0.8' 
NE-SW, homogeneous (or very slightly brighter 
center) with diffuse edges; the "V" shape is seen 
less than 5% of the observing time requiring 
patience to be glimpsed several times; a mag.10 
star 3.5'E is causing ennoying glare at 271x 
(slightly hazy upper atmosphere tonight); two 
mag.12 stars are 1.6'NW and SE.
