Captured M22 globular cluster last week at my weekender ( Bortle 3 skies ) located in the constellation of Sagittarius. This object is quite bright at magnitude 5 and is still quite high this time of the year for observing and imaging
32 x 2 minute dithered guided subs
20 x darks
8”f5 newt on an EQ6-R mount
Canon 600D with Baader coma corrector
ISO 800
PHD2 guiding at 0.90 to 1.0 arc sec error
Stacked in DSS
Processed in Startools

Thanks for looking, comments always welcome

A nice compact globular, nicely resolved, more saturated than I would prefer but colour is something subjective. Stars are nice and tight which reflects those good guiding values. Well done. :thumbsup:

Martin,
Nice one! Did you have a look for the PN ? I had difficulty orienting myself in the cluster - unusually - so it could be worth checking further... Unlikely but who knows.

Cheers

Thanks All !

Unlike previous globs , I had trouble with colour on this object. In hindsight I should have run shorter subs but more of them as my image scale is 0.88 arc sec per pixel (oversampled ) and seeing was ok. When I first stretched the image it was an explosion of stars , way to much detail

Didn’t know about the planetary Nebula, thanks I might look for it

Thanks
