Center of SH2-119 Clamshell Nebula

[gorann]

I got inspired by the recent post and image by  @don4l of this rather rarely imaged nebula, not far from The North American Nebula. So when it finally cleared on Sunday night I pointed my double Esprit rig on it. I had the ASI071 with a 0.79x 3" TS reducer sitting on the Esprit 150 to collect RGB and the ASI1600MM with a 3.5 nm Baader Ha filter sitting on the Esprit 100 (both on Mesu 200), I managed to collect 25 x 10 min with each scope before clouds moved in at midnight. So totally 8.3 hours of HaRGB. Ha added to the red channel (blend Lighten in PS) and also used as Lum. I needed Ha as Lum since I have still not got the right reducer distance figured out so I had long stars in the corners in the RGB image and I had to use Ha to get the star shapes relatively OK (I just posted a thread on that problem). Not enough FOV to catch the whole nebula, which is large, so I aimed at the center.

Any comments and suggestions most welcome!

Cheers

Lovely image.  I like what you have done with the blue.  It gives it some depth - makes it a bit more 3d.

Spent a few more hours of processing. I think the red and the brightness are a bit better now.
