Flat roof garage

[beamer3.6m]

The new house has a flat roof which seems very basic (not tiled etc) which has got me thinking.

If I installed (when I say 'I' I mean builder) a skylight would I be able to raise my scope (via a pier) through the hole. I have an Heq5 with 200p mounted side by side with interchangeable maks.

how big would the hole need to be, would it be waterproof, how would I raise the scope.

I don't care much for visual as looking to move into video astronomy to complement the ap gear I have.

want to keep budget very low. Is £500 doable.

One thing about flat garage roofs is that they can get pretty hot, and cause bad seeing. That could ruin the views for many hours after sunset

fair point. however I have to observe over the garage anyway so is this a mute point.

if I'm happy with this risk then is it doable.

Could be done but there would be loads of vibrations through the mount mechanism so this would ruin any images. Theres also the thermal issues which have been mentioned already. Technically it wont be difficult but I doubt it would be worth the poor views youd get.

Consider this instead of buying an expensive skylight. You or a Carpenter could pre-build a raised hatch, frame in supports at the intended location, mount it on the roof, then cut the interior hole out after its been weatherproofed. This way the integrity of your garage roof won't be affected if the weather suddenly takes a turn for the worst.

I use a ram from here to raise my telescopic pier. max lift seems to be 700mm, don't know if that would be enough lift for you.

why would the mount vibrate once it had been raised.
