Greetings!

First of all, I want to say that my Avalon M-Uno is fantastic, and that guiding is flawless, night after night, despite my Bortle 7 skies in Menlo Park, CA.

Since I updated to driver 7.0x, I noticed two inconveniences:
- The Slew validation which was fixed (thank you!!!)
- The Sync after being park ===> my current problem.

If I start the sync with Carte du Ciel (you know, the connect and then sync with a southern target on the meridian) and if at any point before that the mount was parked, then the sync is reversed, and the mount goes West instead of East. Even if I unpark it before the sync, the problem remains.

I really have to start the mount unparked to make it work.

This is new. It is not a critical issue, but as I finish all my nights' session with SGP parking the mount, it means that when I start a new night, I have to:
- connect to the moun!
- unpark it
- disconnect
- turn off the mount
- turn on the mount
- Sync!

Happy to share my logs of the issues if needed.

Many thanks for your help,

Gauthier

Dear Gauthier
As explained at page 33 of the StarGo User Manual, the PARK feature allows to switch off the mount in the choosen position and restart it, even after many days, without losing the sky alignment.
This mean that after an UNPARK a new alignment is not required.

If your setup is placed on a fixed location, after the UNPARK you only need to slew to a target and start the session.

Furthermore, thanks to the special “Realign to Absolute Position” feature explained on the article linked below, you can store in memory the Error pointing offset obtained and reuse it in future sessions.

Feel free to ask for any further informations.

Best regards

Thank you, this is great news.
That will save me time.
Still, it sounds like the behavior changed with the new driver version, but I now know better!
