Markarian's Chain

[stevewanstall]

Yet another Markarian's Chain image. I tried to ' dither' between shots (with the camera, that is, as opposed to me dithering) for the first time ever, but the tie it takes to dither meant that I lost 30 minutes of images, so this is based on around 80 mins (180 s exposures at iso 1600). The Astrometry images shows why this is an amazing sight in the sky - how many civilisations are there in those galaxies?
