Very well made product providing the closest distance from filters to camera sensor to reduce vignetting with 1.25" filters and the ZWO ASI1600MM-Cool camera. This can be eliminated with Flats. NOTE :- This filter wheel accommodates Astrodon 1.25" mounted filters without any problem contrary to some reports. I am very happy with it.
It works as expected, no surprises

I have the 8 filters option and use it plugged in to ZWO 1600MM Pro hub. Works with all apps I used so far via ASCOM driver.
Great product at a great price.

Got one of these to use with my ASI1600mm pro and it is a great bit of kit. My 1.25 inch mounted Astrodon Filters do fit in this despite being 7.5 mm thick and the stated max for the wheel being 7 mm....but only by a fraction of a mm, the tolerances would not have to be far out to cause a problem.
