Good evening.
While I have been putting together another hybrid image, I could not overlook the very fine 6 filter image posted by Paul a few days ago. So, he happily agreed to collaborate on this image which represents data from 3 telescopes:
AP RH305/STXL16200 for the outer regions comprising Ha (2hrs) and OIII (2hrs)
RCOS 12.5/STL 11000M for tri-colour NB data comprising SII (6hrs), Ha (1.5hrs) and OIII (5hrs)
This was blended with Pauls data comprising Ha (240mins), OIII (120mins), Lum (240mins), Red (90mins), Green (75mins) and Blue (75mins).
Total cumulative exposure time of 30.5 hours.
Hope you like it.
