Markarian's Chain...again.

Here's another go on this subject. I was able to get to a "slightly" darker site than my backyard in the last version with 24 minutes of data.
This version is 160 minutes of data.
ZWO 1600mm cooled camera
160 x 60 seconds, 16bit FITS, sensor cooled to -20° F below ambient.
Processed with Astro Pixel Processor.

I'm happy to say the black bar issue I had in the previous version was not visible in the 16bit FITS.

Very nice image..

Nice image, the camera serves well for both solar and deep sky imaging

Yes it does. Up until the recent virus I was considering making it my dedicated solar camera, permanently attached to the Lunt. But now it's serving well as my DSO camera until things get back to normal.

Here's a crop of the upper left region of M88. It shows a bit more of the spiral structure. I must say my guiding was pretty good that night. I'm not a DSO guy so this is one of my longest and deepest images I've done.

Not to mention this being the upper corner, that .8x reducer/flattener really does the trick.
