Re: Bubbly Detail: NGC 7365


 

Sam,

I appreciate your kind comments.? The telescope is Newtonian 12" truss F3.9?Camera is an ASI 294 MM Pro. Image resolution is 0.34"/px. Bin 1 mode.? Personally I think this should be everyone's first scope!? I.e start at 1400mm and work up, while piggybacking a 200mm for wide field. The mount is a g11 modified for high precision guiding under Onstep control.? OAG guiding using guide QHY camera with 2.4 micron pixels.? When I first processed the data set and looked at images on Astrobin I realized I was missing something. That turned out to be Sii data which is all the fine stuff on the outer perimeter.? So I shot for signal.? The data is processed in Pixinsight. Key to revealing detail is deconvolution. The Astro Imaging Channel has a very good tutorial???from three weeks ago for those who want to take it to the next level! You cannot get this level of detail with OSC camera sadly. When you poroces and stack your data consider using Normalized Scale Gradient. It helps a lot when he moon is about. My sky is New Jersey Bortle 5/4 in theory but I think 5 in practice with the LED lighting that is so pervasive now.
