Hi all,

 

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!

 

cs...John

Thanks guys!

 

Truth be told, if I had known it would occupy such a small part of the field, I might have skipped it!

 

The nebula only spans 52 pixels at my image scale!
