Description

Luminance data  consists  82 subs of 120 sec exposure.
RGB data consist 24 subs  (8 per channel) of 180  sec exposure.
All subs were calibrated with darks and flats and bias frames.
I have added about 1.25 hours more luminence data in May ,2022 and reprocessed this image.
  I used  the Generalized Hyperbolic Stretch technique on this image . Thanks to the people who devloped this technique as it really works well!!
