M 28 (ngc 6626)

GSO 305 mm - Canon Rebel XT - ISO 1600 - 20 min - 10 x 120 sec - OAG - ASI120MC - Coma Corr.

I don't like iso 1600 to clusters with my Canon, but I forgot to change to iso 400 or iso 200. So, some stars and core are saturated.

Well done Jorge, looking good.

Thank you, Joshua. I will try again and I hope remember to set a better ISO. Core of global cluster is difficult to register.
