Hello, I have the same problem as Willi. I use a Mdue StarGo2 Avalon mount. Any solution with polar alignment? I see that when rotating manually the mount using the Avalon interface my polar alignment is not consistent from consecutive run to run and then the mount is not well synced. Could it be just mixing up west and east movements? Any workaround?
Hi, interesting! Looks like an implementation error by Avalalon Instruments. Please, let Stefano know.
- Polar alignment assistent (PAA) with manual slewing
- Opening the small telescope control panel in EKOS/KStars
- Using increments of 30°, West or East.
- Slewing to a fixed RA/DEC value, these days e.g. to 22h, 0°
- Starting the PAA in EKOS
- The PAA starts taking the first picture and does the the plate solving
- Slewing the mount with the telescope control by 30°, e.g. 20h, 0° in the telescope control
- Click on DONE, PAA takes image & plate solves
- Slewing to 18h/0°
- PAA takes the last image & plate solves
- PAA showed misalignment and correction vector.
The RA/Dec values depend on your horizon and the time of the year/day, obviously.
When I click on the left arrow in “Mount control”, the mount is physically moving to the left, i.e. the RA is increasing, but it says at the bottom in the live status “Moving W”, which is not the case! Right arrow button > RA decreases > mount/telescope is going to the right > Status “Moving E”.
The same happens, when I go into the INDI Control Panel / Motion Control tab. Pressing on the [West] button moves the mount East…
Thak you Willi,
I sent to Avalon a couple of emails but I did not get any reply yet. I have also noticed that the Stargo2 driver crashes when moving the telescope with ekos munt control passing the meridian around polaris and you can only recover it after rebooting it.
One question, do you get reproducible polar aligment manually? i.e, if you PA manually with your workaround and then move your telescope and then you do PA again are you still close or minutes away? I do not why I cannot keep a stable PA.
I contacted Avalon and they replied to me today saying they are in the process of looking for a solution. They will be replying to this following post in their own forum, once they have found a solution:
Same here when being BELOW Polaris. Mount/driver crashes! Bummer!
On the other hand, when using the Mount Control from KStars/EKOS, the mount crosses the northern meridian (now above Polaris) without any issues in both directions. No crashes nor interruptions. But the behaviour of the arrow key is inverted! Meaning, I can use and hold the left button to cross the northern meridian, when I let go and press again the same direction button, the mount slews in the opposite direction, that is towards the meridian again. Very weird. Not sure if this is a feature or a bug ?!
I am using KStars (v3.5.9) from my MacBookPro and connect to the indiserver of the StarGO2 remotely.
BTW, note, that I have selected LX200 Classic... but once EKOS makes the connection to the indiserver on the StarGO2, it uses the native stargo2-telescope driver!
Enabling and disabling "Reverse Up/Down" or "Reverse Left/Right" has no effect on the arrow buttons in the Mount Control interface! The mount always moves in the same direction with the exact same status messages.
