Description

Arp 273, one of the "strange" galaxies in the Northern Skies. Close by a pair of large stars - the brighter one is a binary star (giving double spikes at high enough resolution). Arp 273 can be found in the constellation Andromeda and is well know, especially after Hubble took one of its most famous images of it. It consists of UGC1810 and 1813, their distance is about 96Mio LJ and their size is only 1.8 and 1.2 minutes, making it not an easy target for astrophotography ( unless you can use a 40+" telescope...). 
My image here is the result of 3 years occasionally collecting photons - with two different scopes and three different cameras - my poor PC needed 1 1/2 days to complete the APP work successfully.
