I don't have a QSI camera so I might be wrong in assuming that when normally focusing the guide camera in that particular set-up the guide camera will need to rotate to focus. I find that a real pain because I personally find that it's a lot easier to diagnose guiding problems when the guiding chip is oriented so that x=ra. The ONAG has a similar issue. Achieving good focus + camera orientation is nearly impossible. This clever focuser addresses both issues so, and I'll speal only for myself, it will be really good if it lives up to expectations.
I plan to try the SharpLock focusing method using the ONAG which will require starting with excellent focus - given that all the focusing corrections are based on subtle variations in the shape of the guide star. I do have a Borg helical focuser on the ONAG but that solution - whilst it works - has potential for quite a lot of flexure. This new focuser will be rock solid in comparison.
