ABUBAKR REDA

Hello everyone, I am now considering to purchase my first goto mount , i have Clectron edge hd 8" OTA , in my region the only available choices are IOptron CEM 40 and IOptron GEM 45 , and my main interest is Astrophotography (planetary and DSO) . So would u please help me to decide? , i ve seen alot of reviews on CEM 40 but less GEM 45 . My main concern is the payload of the OTA and photography gear . Thanks in advance
