I took this image last winter, but processed it again using PI instead of Photoshop. It is 3.3 hr from a TS Optics 72mm apo ( which is for sale here) and an ASI1600MC. Shot at gain 0, 20 and 30 min subs at -30C. It may still need lightening up? and a couple more hours integration. I really like the MC, and didn't get it for narrow band but it is not a waste of time to do so. I've been on and off the fence on a mono for way better resolution on narrow-band stuff, but I do like being able to still do RGB OSC on galaxies and cluster in short time.

Just to be clear, this is a OSC, with a very similar sensor to the one I have , ASI 294. Hey and the same mount too!  If you do not mind me asking, what were the light pollution conditions like?  I Am not sure what RGB means with respect to OSC.  I thought OSC is by nature RGB. Is that what you mean?

 

Really enjoyed the image.

I forgot to mention that it was a 5 nanometer Astrdon filter. And I don't have a light pollution meter but it's pretty bad I live about five miles outside of Portland Oregon in Vancouver Washington and this was shot in the backyard.
