I didn't think to post this here, until now. This is somewhat in the vein of "Beating Swords into Plowshares": I built a water-proof battery box using an ammo box from a 20mm gun. Here's the build thread.

I have some formica and some kydex and am hoping to make a much lighter dew shield than the one that came with my 6" f5.9 astrotelescope refractor. Bought some flocking from Scope Stuff (very good people to work with)and will use that to line the dewshield if I can bend it enough to make the cylinder. The stock shield/cap is about 3 pounds on this "bulldog" of a scope so I have lots or room to improve the situation. :p

All hail PVC! I have a pair of Celestron 15x70 binoes and was able to make a nifty pair of lens shade/ dew shields for them out of a pair of 3 inch pvc slip connectors. Spray painted flat black they are a perfect friction fit to slip over the ends of the bino tubes

48mm camera filters work fine in 2" eyepieces. They can be had pretty cheap. I just bought this lot.

I'm wondering about the weight of snow or heavy rain on the cover. :question:

the top is a sun resistant tarp 12'x14' heavy duty from home depot. I have it braced like an umbrella on the inside so no problems with rain or snow. If I think the snow is getting too heavy I sweep it off no biggy.I have it very taut with a lot of straps bolted to the rail road ties. More straps than is in the picture. I wanted a 12'x12' tarp but they sent me the wrong one so I used it anyway. Its been up 3 years now and has stood everything but a tornado. heavy rains-heavy snows-50mph winds..

:bow: From the other image, it looked like it just rolled flat over the top.

Very nice!

I figured that's what you were thinking carol.and if anyone is interested in building the dog run observatory just let me know because there are a few tricks I have discovered over the past 3 years that need to be done. if I can do it anyone can. :)

use common sense!! any seams get duct taped and I mean really duct taped. I used all stainless fasteners. All tarps are uv rated..I used 6x8 tarps. On the weather side the roof tarp is bolted on by first bolting on a 1x6x10 to the top of the dog run frame. I used large size pipe straps to secure dog run on the r/r ties..alot of them!and I used them to bolt on the 1x6x10. You have to make that a very secure board as that's the direction of most of my high winds. Its my west facing side.

use plenty of eye bolts to secure the roof tarp to the r/r ties. The tighter the better (but not so much it rips the roof tarp)all the poles used on the inside to hold up the roof tarp are cover on the ends with soft sponge as not to poke holes in the roof.

the boards that you see on the west side of the shed are for a roof tarp cradle in case you want to use both scopes during the night. If only one scope being used you won't need the cradle.

An aluminum door threshold makes a great tube saddle paired with some pvc tube rings and large hose clamps
