Description:
I've strucked out on this galaxy twice before under mag 5 sky.  But tonight...
Gotcha, I think at 60x.  But couldn’t see it at 22x, 30x or 110x!  Really at 
the border of the edge of detection with very faint cigar shape.  It is 
possible that I got the “cigar” tonight because my sky was mag 5.5 tonight 
(base on naked eye epsilon Trianguli) while other nights were only mag 5.  I’m 
sure I saw it because I could see it with averted vision and when I slewed the 
view around, the cigar moved with the FOV.  I noted 3 stars form a triangle 
nearby: GSC 2839:1501, GSC 2839:1258 AND SAO 38001.  If the galaxy would have 
joined the star  GSC 2839:1258, its cigar shape would have form a geometric 
line that is approx. 15-20 degree angle with line between GSC 2839:1258 and GSC 
2839:1501.  The sketch I found on the Web below is very representative of what 
I see except that the galaxy is much dimmer with my TV-102 than the sketch.

This has been a really tough object through the 4" refractor for me, but
persistence paid off!
