A friend and I are trying to help someone inexperienced get imaging equipment set up while in lockdown. He has a new Espirit 80mm Skywatcher and it has a Primaluce Sesto Senso focus motor fitted to it.
The issue is that the focus motor is rotating quite freely on the end of the focuser. I am 99% sure he has simply not sufficiently tightened the machine screw which is supposed to close up the clamp on the focuser boss and lock it in place (Per the picture linked below)
I am just concerned at giving someone without enough mechanical knowledge or mechanical sympathy a direction to go a bit harder then sitting back and watch him make an expensive mistake on brand new gear. I really doubt if I could give him a newton meters torque figure he is going to be able to do anything with that information.
Anyone have any experience with the focuser on the new Espirit 80? The only other option to the machine screw being too loose I could see is that the part the focus motor is attached to is rotating on the focuser, but the video we can see is not quite sharp enough to make that out.
