The Andromeda Galaxy, also known as Messier 31 is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest large galaxy to our own Milky Way. Wikipedia
This is the first image I took with my rig after moving to the countryside and upgrading to the SkyWatcher EQ6R-Pro mount. Setting up the equipment, focusing and doing the polar aligment with the ASIAIR Pro was straightforward and didn’t take too long.

I then used the following tools:
