Looks like maybe I have an older ASI174MM-Cooled camera as it doesn't agree with the pictures or mechanical drawing of the current camera.
Instead of being red and held on with 4 screws as shown I have a one piece black front that screws on, with an integrated t2 female thread facing the scope, that can't be removed.
I need to reduce the back focus somehow. What are my options?
Is there way to change the front to the newer design (red with male t2 threads) or would the low profile adapter sold for uncooled cameras work in this case?
