Here is a full size crop of the Blue Flash planetary nebula in Delphinus. Central star is Mag 14. It has a striking blue color!
At around 40 arc-sec, this little guy really needed more focal length, but the MN190 and the ASI1600mm still pulled in some internal details...albeit tiny...lol!
Since it is a relatively bright object, I'm sticking with an RGB only strategy.
Chroma filters; R=G=B = 90 x 60sec total = 4.5 hrs
Backyard bortle 6 sky
MN190 @ 1000mm focal length and the ASI1600mm pro @ gain 76
Link to full frame on astrobin is here.
Unfortunately, since this is already a 100% full sized crop so you won't see more detail on AB but you can wander the star field. I did not see much else in the background in the way of DSOs...
C&C are always welcome. Thanks for looking!
