Description

I didn't find a lot of images of this target and decided to go for it.  The very faint and rarely imaged SH2-204.  No real name for it and I've been calling it the Prawn Nebula.

This was a VERY challenge SHO target.  There is almost a complete lack of OIII data, see my video showing all the captured data.  SII data was only slightly better.  Even a full 32hrs on Ha was showing a weak signal.  I can see why this is a rarely imaged target.  Even though there is a lot of cool structure and reminds me a little of the Wizard Nebula it is just VERY FAINT!!

My video covering the data!

Reason I have been calling it the Prawn Nebula:

STF of OIII Stack (almost a complete lack of OIII signal):

STF of SII stack, better than OIII but still very faint!:

Then here are 2 close ups:

Controlling noise was by far the hardest part since I had to use very extreme stretching in OIII and SII.

Hope you all enjoy and comments and critiques always welcome!
