That's WAY too long Logan.

In front of the filterwheel I see at least 31mm - the 20mm spacer and what looks like an 11mm spacer. The FW width is looking like at least another 20, so there is 51mm, leaving 5mm...

Distance from the front of the cam to the sensor for the ASI1600 is 4mm for the front ring plus 6.5 from the larger base to the sensor plane, making 10.5mm.

So, by my eyeballing, you are 5.5mm over-long.

I could be wrong, but I do believe this is the case.

EDIT: ok, the 4mmon the face is internally threaded to the FW, so maybe 1.5mm long. Send it here to measure
