NGC 7023 Iris area - would anyone like to share some short FL data?

[geeklee]

I have around 6 hours of Luminance data shot with a RedCat+294MM of the area around the Iris.  I don't have great skies but I'd like to try and combine it with some RGB if anyone has something around the same focal length.  You're welcome to this Luminance in return.  I may not use the data but am interested to try.  Thanks.

Focal distance - 246.53 mm
Pixel size - 4.60 um
Field of view - 4d 16' 34.5" x 2d 53' 11.3"
Image center - RA: 21 05 59.102  Dec: +68 10 24.28

Hi Lee, I won't be offended if you decline this offer as it isn't up to much...

139 x 1 min captured with the RASA8/QHY268c, in the mid summer of 2022. The peripheral stars are cr*p and imaging in a barely dark sky has clearly resulted in a lot of issues. If you still want it let me know and I'll PM you a link to the un-processed fits file or whatever you want.

That would be awesome, thanks Steve.  I'll drop you a PM.  If anything I'm more worried about the image scale and quality of my Luminance!  Yours looks like its still has bags of signal even in those challenging conditions (RASA hoover!)

Thanks Lee, I've sent you a link to a couple of files.
