When is a shed too hot for storing a scope?
What damage can it do in the long term?

Metal ( ? ) sheds are tricky places for optics as ideally they are not insulated and your optics can often end up coated in water every sunrise and depending on the prevailing weather conditions and time of year , and may not adequately dry off every day. Large optics suffer from this problem . A 15 watt light bulb mounted on a wooden plate in the mirror box can help. However you want the shed to get rid of its heat fast at sunset, so insulation in the walls isn't good . Unfortunately the requirements for a good observing location and scope protection are actually in conflict I'm afraid !
