Hi Grant,

I own 3 of those SX Midi wheels and also a larger one for 2″ filters and I have only had the droop issue when I was connecting one to a small WO71 APO with a fairly heavy ATIK CCD. I think it was the CCD that did most of the drooping in that case!

The other scopes I use have much more robust focusers such as Moonlite on my C9.25, and the Tak focuser on my Tak 85. These focusers are designed to carry much heavier loads.

I don’t think that the SX Midi FW is a particularly heavy example of a filter wheel, so I don’t think I can say anything that will help with your current setup. I think I would have to fall in the ‘buy another focuser’ camp!

Cheers
Ian.
