Staphan's Quintet in wide field of view - maximum what my camera can achieve in current set up.

Material registered during 5 night sessions under variable sky and seeing conritions.
But luminance was collect during really nice seeing which allow to reveal some nice detail on the galaxies.

Also there are two very interesting galaxies on that picture. PGC141041 (on the bottom of the picture, size 18''x16'', brightness 18,45mag) and PGC 141039 (close to upper left corner of picture, size 19''x16'', brightness 18mag).
This first galaxy has very interesting "donut" shape athough in catalogue it's classiefied as spiral (Sb)

Close to NGC 7320C you can find tiny and dark galaxy J223621.54+335748.0 with 21mag brightness. This is only to show of magnitude range of photo - which is achieveable with short subs :)
