About this image

Only 20 minutes imaging time to capture this connected galaxy pair, a suggested target from Callum / Deep Sky Section for this month. I was just finishing off imaging some other targets when I decided to give this a go. Several bright (mag. 8) stars, totably HD 217855 in the centre of the image were rather over exposed but some detail can still be made out in these very distant (~200 million l.y.) galaxies. Hubble captured them nicely a couple of years ago.
