My Proline camera has the sensor 21.5mm deep in the camera and the filter wheel is 21mm thick with the filters roughly half way so that would be 33mm.
For full frame 50mm round would work.

Its tricky as you have to know what the clear aperture of the mounted filter is.
45mm is a fairly long way.

Thatís assuming you use a ZWO filter wheel.
I use my FLI one with mu ASI 183mm Pro.
Not that the tiny sensor outs any stress on the peformance of the filters sizewise.
