Is the idea to keep the inside temperature the same as the outside and/or will the temperature difference affect the telescope. The observatory will be used primarily for photography. Any advise would be appreciated.

I just used second hand colourbond sheeting with the corrugations horizontal. This is suppose to create a little shadowing when the sun is high reducing the heating slightly. I haven't lined the walls. It cools off very quickly. Insulation might slow down the cooling off. Professional observatories refrigerate the inside during the day to beat the cooling off. This is a bit over the top for a little observatory.
