@Butzzze Where is it?

[Michał Mosdorf @spockm]

M81 captured with RC6 and ASI533 from Warsaw. 27h on L-pro and 16 on L-extreme. #Astrophotography

@astro_addict Check this thread: https://t.co/edPZBy0I0J it is in Polish but you will be able to easily translate most important answers.

@astro_addict Alternatively use Astrometry. Based on that you will see what is the delta to nominal FL in mm. Now you will have to adjust this by changing the distance between primary and secondary mirror. This is done by screwing central screw on the secondary mirror.

@Butzzze What you are seeing is probably related to stiction. In my case meshing of the geers was soo tight that belt was streathing too much while trying to correct the Dec backlash.

[Michał Mosdorf @spockm]

@Butzzze I would suggest that you loosen the Dec gear meshing. Also try the unidirectional Dec guiding. This is the approach that helped a lot in my case with cem26.

Just tried mosaic from multiple shots taken with qhy462 and Skymax102. #Astrophotography

California Nebula from winter months. D5300, WhiteCat, Star Adventurer. 8h.

@Butzzze Hi how did you manage to solve dec backlash? I have similar problems that you had.

[Michał Mosdorf @spockm]

@Butzzze I have seen this issue mentioned on cloudy nights. In my case I have used the mount ony for 2h so still too early to have any conclusion.

[Michał Mosdorf @spockm]

@Butzzze Did you talk with ioptron about that? I home I will continue testing today.

[Michał Mosdorf @spockm]

@Butzzze Thanks. I will probably try gear meshing. I must say it is quite worrying that Dec guiding is soo bad in auto mode.

[Michał Mosdorf @spockm]

@Butzzze How did you reduce dec backlash? I am heaving similar issues witm cem26.

@626Corp @mat3oosh @OVHcloud Thx
