Hi,

I had a great time imaging last night. Got Saturn, Jupiter, Mars, Venus and the Moon all at F30 with my Edge HD 9.25 and a ZWO 1600 mmc.

At the end of the night I thought I would try Saturn at F20 to compare details. However whenever I centered it in the camera it would slowly drift off-screen. I could stop the drift sometimes by slewing in the opposite direction a bit.

I already had some quality imaging time so it was late, I gave up and went to bed.

Tonight I setup again (with fully charged batteries) but could not get rid of the drift. Basically after getting aligned in AZ mode with the mount level according to the bubble whenever I slew to an object it will slowly drift off screen, making imaging impossible.

It takes about 20 seconds from a centered position to drift across the chip, which is a 22mm diagonal chip.

Any ideas because at the moment the mount is unusable for photography if it behaves like this.

Cheers
Paul
