Trifid Nebula, M20 in 16 Minutes

Trifid Nebula, M20 on Aug 21, 2020. 65×15 sec, Gain 30, Offset 218, Optolong L-eNhance filter, QHY183c at -10C, Televue TV-85 at F/5.6.

Here’s a very short run I did on the Trifid Nebula.  An extra short quickie with only minimal processing.  I was interrupted by a couple of young gents who saw me imaging in the front parking lot and wanted to see what I was up to.   They also wanted to see Jupiter, so I obliged.  By the time I got back to the Trifid, it was already about to go behind a tree.  Oh, well…

I am hoping to get this object with about an hour of exposure at least, if not more.  To that end, I added what I had taken before with my SN8 and Canon XT camera to see how it might look.  The additional data was 54 minutes of 3 min ISO 800 subs.  It is about a half-n-half blend:

Combined data from SN8 scope and Televue TV-85 scopes, about 70 minutes total.
