M57 in 1200" subs (May 2022)


Here is M57 with 1200" subs.  Through an Astronomik CLS filter from my site, 1200" subs put the nebula itself at 75% to the right on the histogram.  Much more exposure would have started whiting out the primary target.  Anyway, M57 is a lot of fun.  You can see in this image a hint of the expanded shell if your monitor is set to show relatively dim things.  This is 12x1200" through the 203mm Synta ONTC Newtonian at f/4.9 and an Astronomik CLS filter with the Atik 460EXC camera.
