M22 under a Full Moon
Apart from some light to medium wind gusts , seeing conditions were OK last night in Sydney so decided to capture one of my favourite globular clusters M22
in Sagittarius. M22 was also up fairly high in the northeast so that helped a bit with moon glare
Focus was drifting a bit about 2/3 through the capture so waisted about 15 minutes to refocus ( had to discard 15 subs )
