I can't easily see straight up because as a newbie I build a hyperbolically curved (to keep under councils 3 metre height rule) dome roof that only provides a viewing window from 15 degrees above the horizon to vertical. You really need to go 15 - 20 degrees past vertical to allow a German equatorial mount to see vertically, as the scope is of course not directly above the mount but in my case almost 30 - 35 cm away!
