I'm kind of out of my comfort zone here, but one thing comes to mind.

"altitude will be indexed with 0 equal to the orientation where the optical tube is perpendicular to the azimuth axis."

Some celestron Alt / Az mounts have NexStar handcontrollers. I'm not shure how the aligment procedure is for Alt / Az mounts, but if altitude is indexed to 0 equal to the orientation where the optical tube is perpendicular to the azimuth axis. Then on a alt az mount the tube would be pointing straight to the Zenith with it's bottom to the north. Would that not be 0 (or 360) and 90?

Not sure if that made any sense. I might not be getting the big picture here..

Ah okay yeah that word makes a lot of difference, I guess I'm just used to GEM alignments. At any rate, the only reason I added Az/Alt stuff in the driver so that custom parking is possible. But I guess what I can do is calculate Az/Alt myself. Let me go ahead and do that and see if it works.

Yes! Super nice.

Parked to 1 / 181 <(''<) <( " )> (>'')>
Just what i was hoping for :)

Thanks for the fix.

That's half the test. Please turn off power, turn it back on, then connect to the mount, then unpark, then slew to a target, does it slew correctly?

Parked mount -> disconnect equipment -> stop indi -> hibernate mount -> power of mount -> power on mount -> start indi -> connect -> unpark -> slew -> capture and solve for good measures - All working. Forgot to debug to log, but looks ok. No need to remember to sync after unpark :)

Edit/ Also work when stopping indiserver and rebooting server and client when mount is hibernated.

Just one thing i noticed. The mount does not stop tracking when parked.
This is not a problem if the mount is hibernated right away, but if it's parked for a while before shutting down it will have tracked a distance.
When the mount is unparked it wil sync to the park coordinates, making it slightly unsynced.

I looked trough the NexStar Communication Protocol that you linked to, and there is a "easy" fix.
Tracking Commands 
The following commands retrieve or set the tracking mode. 
Depending on the mount type, following tracking modes are available: 
0 = Off 
1 = Alt/Az 
2 = EQ North 
3 = EQ South 
Note
:  On the CGE and Advanced GT hand control versions 3.01 through 3.04 the value for EQ North is 1 and EQ 
South is 2.  This has been corrected to match the other models in current hand control versions. 
Command Function 	PC Command 		Hand Control Response 	Applies to Versions 
Get Tracking Mode 	“t”                    	chr(mode) & “#”        	2.3+ 
Set Tracking Mode   	“T” & chr(mode) 	“#”                   	1.6+

The current tracking mode would have to be stored to .indi/Celestron GPS_config.xml "or something" with the Get Tracking Mode method before setting tracking mode to 0, so it can be retrieved when unparking.

I have tested parking the mount and waiting ~20 mins to see that it drifts, then resetting, parking again and setting tracking mode to off in the hand controller. Waited ~20 mins and no drift.

Think this would be a nice update to get even safer parking. Will of course test it if you get the time to implement it.

Should possibly posted this in the feature request page, but it was on topic, so i posted it here.

When parking Tracking is set to off, but when unparking it is still off. Tried to slew, track to target and still off.
When disconecting, stopping server and setting it to EQ-North in nexstar, it will be set back to off when reconnecting to indi.

In file ~/.indi/Celestrong GPS_config.xml "TRACK_OFF" is set to On, and rest is set to Off
<newSwitchVector device='Celestron GPS' name='TELESCOPE_TRACK_RATE'>
  <oneSwitch name='TRACK_OFF'>
      On
  </oneSwitch>
  <oneSwitch name='TRACK_ATLAZ'>
      Off
  </oneSwitch>
  <oneSwitch name='TRACK_EQN'>
      Off
  </oneSwitch>
  <oneSwitch name='TRACK_EQS'>
      Off
  </oneSwitch>
</newSwitchVector>

Sorry. New test with new confiig file.
Tracking EQN, Park tracking set to of. Unpark tracking set to off in Nexstar. Disconnect and vi Celestron_GPS_config.xml and tracking set to TRACK_EQN.
Think tracking was of in nexstar from last test.
