Hi Sam,

That's great news.

I have noticed that these cameras no longer come with UV-IR cut filters. It comes with AR coated windows. Maybe include extra UV-IR cut filter with the camera. Let the user decide which filter to use.

I notice that it requires some kind of spanner wrench to remove the black ring that supports the window. Do you know the size of the spanner wrench needed to remove the black ring or you could sell the wrench under accessories.

I find it more convenient to have filter (or window) mounted inside the camera instead of using external filter. Not everyone including myself have equipment or convenience of attaching external filter.

In my case, I use T-Thread to screw the camera to TeleVue T-Thread adapter for TV 2x/4x Powermates. You can see why I prefer having window-filter mounted inside the camera. I could buy and use 2" external UV-IR cut filter and screw to TV PowerMate but I still prefer filter-window inside the camera.

Thanks,

Peter

Is the glass window in the camera the same size glass as in your 1.25" UV-IR cut filter? I am thinking of removing the glass from your 1.25" UV-IR cut filter and replace the AR clear window of the camera with UV-IR cut filter glass. Would this be possible?

Thanks,

Peter
