Thinking of making an observatory in my roof to get over the trees in my garden, first of all, is there anyone that has built/has a roof observatory? Building one will give me the hole sky to work with but i really dont know where to start, my roof is triangle shaped and im thinking of adding a pretty big window that can open itself when im imaging, my telescope will pop out the window just able to peek over the top of my roof. Im afraid of the vibrations its going to have but considering ill be in my room far away from it, i wont see any problems... I hope. Is this a good idea or should i just chop down the trees( hopefully not )?

The potential issue here is the heat rising from the roof at large, and the opening itself. If your viewing is low power visual or AP, it may not be an issue at all, but if higher powers are used, expect an additional variable to affect the seeing. Vibration is less of an issue if there is no movement in the vicinity of the scope. There certainly is an attraction to be able to view without leaving the house.

 

Don't chop down the trees, the best viewing is around the zenith anyway. I'd prefer (and have had) higher quality views though restricted to overhead only, rather than whole sky availability that includes poor images closer to the horizon.

My flip-open sky access in a roof dormer. It was fine, though rather cramped, for low power views and AP.
