Shots processed using Astroart, Aip4w and Photoshop Lite. Lots of fiddling about trying different things. Part of the problem was probably due to the moon being out which lead to a blue hue and over exposed blue frames. The wind was also quite gusty but tracking was quite good considering.uided using MX5C on Celestron 80mm using a 3 x teleconverter to give f15 and focal length of 1200mm. Guide exposure of 2 seconds.
