Roof top observatory in Indianapolis

Some questions - what is used for the base of the pier, and does it extend down to the ground? Do you have any trouble with thermals rising off of the hot roof after dark?

One element that provides some stability from vibration is that the astrograph is operated remotely from my study downstairs. All USB or Serial/USB cables are fed into multiple USB extenders and then through cables downstairs.
The main problem is not vibration but wind, clouds, jet stream. If we have significant wind, I am out of business for the evening. Indiana is not the best place to do this kind of work but I like the idea that I can set up an imaging sequence and sit and watch movies/streaming video with the wife. It has improved our relationship from the time that I used to have to sit up there and do everything manually.

It would sure be nice if CN would resize images for us when we upload if they're too big (hint hint).

I have a different "stealth" design observatory installed on the top of my attached garage. I see from your posts you have a problem with wind shaking the very exposed telescope. I also had this problem until I installed "flip-up" plywood wind screens. They completely prevent any telescope vibrations even during very windy nights.
Here's a shot of my rooftop stealth observatory ... it's been in operation for almost 14 years:
Good Luck with your observatory ... it's a real beauty!
