One of the superthin galaxies on my list came into my observation window.
NGC 4244 (Silver Needle) or Caldwell 26 3, is 12 Mly away and part of the Canes Venatici I Group, a galaxy group relatively close to the Local Group.

I got the nucleus out quite well, I think, but the details suffer from the very poor seeing this night.
Fortunately it is very bright so the moonlight didn't affect the result too much.
The bright 6.7 mag star HD 107341 near the field sent a nasty spike into that image so I was forced to crop it by 20%.

Hope you like it!
