About this image

The image shows the outer shell of M57, NGC 1296 and also CGMW 5-08786 and 2MASX J18530959+3305385.

Processing was a logarithmic stretch extract from Maxim DL followed by selective reduction of exposure levels for the bright ring then increasing the inner section of the Ring.  
I was not aware of  CGMW 5-08786 or 2MASX J18530959+3305385 until I processed the image, and they stood out as odd. I checked the location using Aladin and then NED gave me the identifications.
The data was collected over 10 nights between 4th to the 22nd May 2018.
The image is a LRGB Composite of ...
