More like thinking outside the can! Garbage can that is. Very creative!

Painting it white will help. You could also try a low voltage exhaust fan.

Very cool indeed!! Love all the wonderful ideas for observatories shown here on CN. No observatory is ever to large or small as long as it is used. :)

About heat control, definitely painting it white will help as well an exhaust fan as others have suggested.

Did you put up the fence at the same time to block out stray light too? How high is the fence?

Do you leave it there all the time, even in the rain? Also, what about summer, gets pretty hot where you are.

Very cool idea!

rec, I had a friend help me put the fence up, it sure cuts down on the wind and blocks out all the light. its right at 6 1/2 feet high and measurers 13'x 17' off the back door to my garage. it has smaller slates in between the larger ones for zero light. I really think I might wind up purchasing one of those silver covers in order to cut down on the heat. heres some photos of the fence and concrete slab.donnie

What you need is a vent on the top that will keep rain out, something like THIS . Home Depot carries them. I would test it for how well it controls leaks.

For heat control I shade with a sheet of burlap a foot or so away. I also monitor heat and humidity remotely.

A fine piece of red-neck engineering! The plastic garbage can is a signature element of such design.

Solar cell power boat vent. I used 68 of these on small satellite self contain units and never leaked or replaced. Motors would go out and once the cells quite (5 years) just hook up to 12volts and no leaks 12 years later. They are low profile and small, that is why I suggest them.
