Description

Wide field shot with DSLR and 300mm zoom lens only on telscope's tracking mount with autoguiding.
45 x 4 minute exposures at ISO800

Version D - 26 Apr 2019 - As a relative newbie, I've just about cracked some main techniques on the acquisition side, but was struggling with understanding the intricacies post-processing - see previous poor attempts! I discovered StarTools and the post-processing tracking, modules and behind the scenes operations make the whole process easier to understand, for me anyway. This is my first reprocess attempt with StarTools and I'm very pleased with the result, compared with previous versions.
