F-ber Diameter 3.94 inch/100MM w/ 4 Holes Acrylic Indoor/Outdoor CCTV Replacement Clear Dome Camera Cover Security Dome Camera Housing

arrived well packed so it had no scratches or other marks

I've built about 6 AllSky camera systems over the years, for myself and for friends. Tried a few other domes in the past, but they don't stand up over extended (years) time. I've had 2 of these out in the elements for a few years now - 1 is a little discolored (but doesn't damage the camera's view), and 1 has a few little micro-scratches from wind, birds, mother earth. The size of these seems to fit perfectly for my designs too, even allowing a dew-heater-ring . As others have said, bright moonlight does create glare/reflections, but that's not specific to these specific domes, the glare is unavoidable regardless the dome unless you're buying optical glass, even then, I'd think its still unavoidable. So 'moon glare' should never be a reason to deduct a star. I'll keep coming back to these domes for my future builds & dome replacements.

This dome was accurately described in the product page, and the dimensions appear to be accurate as well. I had a very specific use case and it was met well. The globe seems very transparent, good for camera use although I did not use it for a camera. It feels fairly sturdy and not likely to break or crack with normal use.

I'm using this to build my All Sky Camera with an ZWO ASI 676MC camera. It came unscathed, but I've managed to burnish a couple of rub marks already before mounting it to the enclosure. I'm sure it's no more prone than any acrylic dome, but they're pretty fragile in this respect. Still happy with the dome and it's easy to mount with the flange and 4 pre-drilled holes. I'm using #4 screws.

Optical garbage. Distortion clearly visible, so I took a picture of grid paper that shows just how bad it is.
