Took this last weekend. Took most of the week to process.
Built up from the best quality 500/3300 sub-frames using regitax multi-point alignment (40 points).
Ate up about 20 solid CPU hours. (and I had to start over once, don't want to talk about it!) Then a couple of hours final tweaking.
Scope 12" Meade LX200. Camera Skynyx 2-1M.
Vallis Alpes To give you an idea of what was involved, here is a average single raw frame example:
