Description

Last night was textbook perfect for imaging - zero cloud, unlimited visibility, 15°C, no wind, and a 0% new moon - it doesn't get much better than that

This is my third attempt at imaging NCG253, hopefully an improvement on my original image, and my second attempt, taken exactly one year ago.

I was inspired by the striking counterpoint between NCG253 and its neighbour NCG288, so have posted a narrow-field version here.
