The OAG will give "bad" stars and the guiding software should have no problems with guiding on them.

Hi Gaby,

If the whole setup, OAG - EFW2 - Spacers  and Cameras are well fitted, so no flexure, then the only problem is coming IMHO from the Backlash and the PE of your mount..

You should perhaps try to reset you worm gear space to obtain a better result and even try some PEC with PemPro, a nice soft available for some bucks!

Best
