Bubble Nebula -NGC 7635 and M52
Anza, CA
M52 and the Bubble Nebula. Taken with a modified digital rebel through a Vixen VC200L and Vixen 0.64x reducer with an IDAS LPS filter, this 16 x 10 min at ISO 400. Mount is a Losmandy G-11 Gemini with a Borg 77mm achromat with 2x barlow and a modified web cam as a guide scope, guiding provided by GuideDog. Processed in ImagesPlus V2.75 Beta 2D. I normally use 6 min sub exposures but was experimenting, I think I prefer the 6 min compared to the 10 min, less noise and certainly less amp glow to deal with, now I need to work more on the post-processing. Focusing accomplished using EzFocus prototype and DSLRFocus autofocus.
