Hi,
has anybody had this problem as well?
I use an AM5, TS CFAPO90 with 0.8 reducer (focal lenght 432mm), ASI 2600MM, ASIAIR PLUS, no counter weight (less than 10 kg)
guiding camera at separate 160mm guide scope: ASI 462 MC with L filter

I constantly have the problem that within 1 hour before MF the DEC axis is lost (star lost .... mass changed). As a result ASIAIR selects obviously another guide star and stabilizes, though the image is shifted. It looks as if the telescope moves South by a constant amount (typical 5% ... 10% of FOV) and stays then constant. This may happen several times. An example ist shown in the figure showing two ghost images. North is to the left.... I have a lot more examples.

Before that failure and AFTER MF everything is fine, images are at their suggested coordinates (Autorun, Plan).

In the following I put sections of the logs. The PHD2 parts clearly show, that ASIAIR guiding tries hard to shift the telescope north immediately before, but it fails. It looks as if the guide star moves out of the box.... S/N of the ASI462MC is not the problem. I suspect a gear issue... Any comments and replies, ZWO too..

c.f. image 4 before MF : 2 additional „ghost“ images

PHD2: log file messages,

before problem occurs; DEC corrections increase, but cannot compensate DEC issue, star moves obviously out of box , star lost......

after selecting new guide star: neutral guiding until next case....,, Image shifted though

AFTER MF: everything is normal, image is not shiftet any more, corresponds to chosen image RA/DEC image coordinates when starting AUTORUN or PLAN
