Cooling a tin shed observatory in summer ?

Thanks for the comment but i think you must be the genius looking at your inventions :80mm refractor (made from an old Coke bottle)
2x40mm Binos (made from two toilet rolls and four plastic magnifying glasses from Go-Lo).
Solar Scope (made from a shaving mirror and a windscreen wiper motor)

I'm just a lateral thinker!! Hope my idea works for you even if only as a stop gap.

I would definately go with the sail cover suspended a few feet above it myself (set up on rollers like a pool cover say). I would skip the shade-cloth though and use something highly reflective like an aluminized tarp. These come in big sizes and have convienient holes already in them, cheap too! A good shade sail system will prevent the heat from ever getting to your shed in the first place, so you wont have to worry about insulation, fans, etc.
