Description

Early steps in ramping things up a bit from the easiest nebulae and moving to a larger scope too.

This Medusa needs more integration from its initial 3hrs or so, and the balcony location for this scope means more dropped subs due to vibrations (I suspect). The weather's closed in now so it will be a while before any refinements. Posting as a starting point. It will be better to put this larger scope on firmer ground too. 400mm seems to work fine on the balcony, but 770mm looks to be too much of a stretch.

Description: Added another hour or two on each filter, slightly less stretch, and first time I got EZ deconvolution to work. Cleaner and clearer, though the colors less nice!
