Thanks @robertp. I wonder if ASA has any "residual" memory in the mount that can influence the behaviour of servo drives.

Hello, I have been using my ASA DDM60 for over a year without issues. Unfortunately after last session in April the mount started to behave strange. It finds the home position, then I sync it to a star, then the tracking starts, but when I make a photo, the stars are lines, not points. When I stop tracking and make continuous 1 second exposures, I see stars moving as the the sky moves. When I start tracking the stars are moving in the oposite directions which means that the tracking speed is higher than it should be. At the same time the position of the telescope shown in Autoslew does not change as the mount would be pointing perfectly to the star. Location of the scope is taken from the GPS and is correct. Local time is OK too. Servos tuning completes without errors and manual tuning shows that the mount behaves as it did before. Balance is OK. The mount is set on a permanent pier and i did not change its position. I did the factory reset, new Autoslew installation, clean installation with deleting data files, and I tried to use another PC. This did not help. Do you have any idea what else I should try to fix it? Regards, Andrzej

Hi @Wojtek Gdańsk, do you dither via NINA? Regards, Andrzej

Thank you for your answers. Slowly I am getting used to Maxim but I will try N.I.N.A when the weather allows.

Hi Wojtek, any success? I am just starting with ASA DDM60 and would like to have an alternative to MaximDL. Do you use Sequence pointing files with NINA? Regards, Andrzej
