Very simple, straightforward dew shield for the EdgeHD800. Slide in and twist to lock.

I wanted a rigid shield because I'm looking to add an automatic (ASCOM controlled) flat panel system to the scope soon.

If you're worried about heat deformation, you should print using PETG, though I just used PLA+. Probably a good idea to flock the insides with something like felt paper you can get on Amazon.

I've also uploaded a "with skirt" version for those who worry that dew accumulating on the surface of the shield could trickle down and make a puddle on the corrector lens. Living in the desert, I wasn't thinking much about actual dew :D
