Polarizer & Neutral Density

I would like to connect the MPCC Mark III to a ZWO ASI1600MC-Cooled camera that has 6.5mm back focus.

Do you sell the necessary spacers to do that?

Will the DSLR hot-shoe adapter that works with the Sky-surfer III, work with the Sky-surfer V? If not, where can I obtain a hot-shoe adapter for the Baader Sky-surfer V?
Thanks for any information.

I am interested in using the T-2 32 mm prism diagonal on my Orion ED80 f7.5 600mm f.l. refractor (bought in 2009). It has a 2" Craford focuser that I would attach it to. I would like to know what adapter I need to attach it to the focuser?

The focuser comes with a long 2" eyepiece holder that I want to remove to reduce the focal distance to the point of attachment to the focuser. That leaves the focuser's exterior threads exposed. The exposed threaded tube's dimensions are: ID = 2" OD = 2-1/8" exposed length is 3/8". I can't find a spec on the threads. but I count 10 threads in that 3/8".

My goal is to gain inward focus, increase contrast and clarity, and convert to the clicklock eyepiece holder. My largest eyepiece is a 32mm Optiluxe. As light conditions limit to planetary, I doubt I would get a longer f.l. eyepiece.

I have a Steeldrive focuser motor which works fine except that the temperature never has been detected by the handcontrol or SteelGo/ASCOM. The manual suggests to fasten some screws, which has been tried without success. Do you have a solution to this problem?

How secure is the nosepiece when coupled to the diagonal body? Is there any risk of it loosening when subjected to heavy loads with the diagonal oriented horizontally?
