That's it.

Just two warnings.

- When you use the control pad and the telescope arrive to North Pole, it stops and starts moving in the reverse direction, because FS2 changes his internal state and North is in the other direction. So, you must be alert to stop pushing the N button once +90 was passed.

- Side pier is in the Dome driver because Dome need to know pier side in order to positioning right. If you have no Dome, you don't need to inform.

Future improvements if someone wants/have time to implement it in FS2 driver:

- Detect when FS2 croses North (South) Pole and register the pier side change.
- Add to the FS2 driver a function to flip meridian. If the movement to North was done by software I think the FS2 internal state with change also, but not sure.
- Add functionality for avoid colisions with the mount.

Hi,

I'm the author of the FS2 driver for INDI.

The problem with FS2 is it doesn't provide a pier side status in the LX200 protocol, so the driver can't know which side it is. On the other hand, in the Dome drivers, you can manually inform which side the telescope is, in order to solve this issue.

By the way, you can flip the pier side of the telescope with FS2 without turning off or realigning. Just "simply" use the pad to move the tube to north until it crosses the north pole (south if you are down under). At that point FS2 flips his internal state of the pier side and you can slew normally and it will go to the other side of the pier. And don't remember to inform to the dome driver the new pier side.

I'm trying to slave the dome with the most recent version and I get this message:
2017-09-10T20:17:02: GetTargetAz failed 0
2017-09-10T20:17:02: Geographic coordinates are not yet defined, triggering snoop...
2017-09-10T20:17:02: Active Snoop, driver: Astro-Electronic FS-2, property: GEOGRAPHIC_COORD
2017-09-10T20:17:02: Dome will now be synced to mount azimuth position.
2017-09-10T20:16:54: Calling Update mount to anticipate goto target: 297.911 - DEC: 8.91504

So, for some reason, my mount driver don't return geographic coordinates. I think this issue appeared some time ago and Jaseem solved it.

Dome driver also has a property to specify pier side manually.

It would be nice, if pier side is not provided by the mount driver, use de dome property instead.

One possible implementation is when snooping for mount side of pier and a value is get, modify dome side of pier, and then use the last one for calculations.

Click the Apple icon in the upper menu, at the top left of the screen and select "About this mac..."
Then push the button "System information" (or somthing similar, my OSX is in spanish)

In the Hardware section find USB item. The you will find all your USD devices, including your usb adapter.

Hope this helps you.

Finally I had time to take a deep look to Dome Sync and found some bugs in dome position calculation.

I corrected and a new version is available. Also I corrected google Spreadsheed son you can check the results there also.

Scott, Do you have a debug log?

It can be useful, because many partial calculations are logged.

Sorry for not been more supportive but I have not many free time this days.

I forget to say if the telescope is at west of the mount, then you need to put OTA negative.

Hi,

I created a google spreadsheet with all the calculations for dome sync.
docs.google.com/spreadsheets/d/1FWN0S7kG...HIo/edit?usp=sharing

Editing the blue cells you get the telescope and dome azimutal coordinates in orange cells.

There you can check if INDI dome get the same result or if there is something wrong.

The difference with Toshimi Taki's solution is my solution allows E-W telescope adjustment.

Ferran

Hi Scott,

All measures must be in meters. But I suppose if you use the same units in all the measures I must work

I expect to have time this weekend to take a look at your problem.

Ferran
