M57 (April 2020)

This is 12x360" with the Atik 460EXC through the 203mm f/4.95 Synta-ONTC Newtonian.  OK, another Ring Nebula---I will say this, though.  While I was shooting, I was also observing the Ring with my 6" Spooner Parallax Newtonian.  The Ring looked magnificent in the 6", though I could see no color.  Here's a monochrome image that is deeper than I could see but in some ways similar.  I used it as Lum for the image above.  Stars are pretty deep here, down to around mag 18.
