M31 Andromeda 5-7 September 2012
Three clear nights on the bounce - whatever next?! :)
Took advantage of the weather to give this a really good crack, something I've been waiting to do since the arrival of the ED80. This is full frame, so the focal length is ideal. As near as dammit 8 hours total exposure, made up of various sub lengths and iso settings. The variation in iso seems to improve the overall noise in the final tif, so I was able to stretch this a little further (some would say too far!). Not sure if it's a little too contrasty - all a matter of personal taste I suppose. Overall, I'm very pleased with this :)
