4inch/100mm Clear Acrylic Dome

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.

Who would have guessed so many people are building all sky cameras? I've had my camera in service for a couple of weeks now and the dome works well. A bright moon produces glare, but I thing that is unavoidable.

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

The dome is very nice for my all-sky camera. The dome has 4 pre-existing holes in it. It would have been nice if screws came with it, but that's ok. I already had slightly larger screws so I drilled the holes a little larger. I notice a glare with the dome under bright lighting, but this won't be an issue for me since I plan to use it only at night.

I needed a dome for an AllSky camera I was building and this fit the bill perfectly!

Nicely made with no blemishes. Was very well packaged with dome well protected. It does scratch fairly easily so beware when assembling. Good fit for a 4 1/2" PVC pipe cap. Answer to my own question: the mounting holes work perfectly with M3 bolts but #6-32 bolts are slightly too big. You can drill holes out a bit for #6-32. I also recommend nylon screws as opposed to metal to allow some "give" when mounting the dome.
