I do not guide at F840 with my 10micron mount. Stars are pinpoint sharp with 5min subs without dither.
If I activate dither in SGP:
- Guiding interface>Direct mount guider
- Dithering options>Dither=0,1s or any other higher value
- Settle at < 0,10s
- For Xs
I always get trails on the brightest stars, as if the sub will start before dither will end, or as if sub still active when dither begins. Longer dither time => longer trails. Increasing settle times or reducing settle pixels does NOT change anything.
I have installed the latest version of oficial softwares, drives and firmwares:
SGP 188.8.131.52, ASCOM 10micron 184.108.40.206, ASCOM Platform 6.4 SP1, Mount Firmware 2.15.14
Thanks for your help
