Description

This very weak object, a supernova remnant in Cassiopea, is catalogued as Abell 85, CBT 1 or LBN576. I only collected data in H-alpha and O III narrow bands. Spaecially the latter one is very weak. Maybe there is some decent signal in other bands (like S II or N II) but I didn't have the patience, or the filter. In any case, a beautiful and inspiring object.
