| 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. |
