The link posted in your reply Sean gives me a 404 - page not found. I have looked extensively at the current pages for the OAG and the drawings that are included. If the number that sky.tones and myself are looking for is in that information - it is not clear. Please check again and respond with the information.
I specifically want to know the minimum distance from the prism to a ASI174MM mini sensor. My imaging camera is an ASI1600MM-Cool with the EFW 8 position. From what I can tell reading the drawings here
https://astronomy-imaging-camera.com/product/zwo-oag
it is 7mm from the prism to the back flange of the OAG. Combine that with the 20mm depth of the EFW and the 6.5mm depth on the ASI1600 - it is a minimum of 33.5 mm from the prism to the sensor of the ASI1600MM if I connect them together with no spacers. So what I need to know is if that is compatible with the prism to ASI174mm sensor installed in the OAG.
