I have noticed that there is no option for SGPro to automatically unpark the telescope, enable sidereal rate and start the plate solving to center an object, for example on my EQ8 pro, I have EQMOD have the following
Defined Park Position - This is used for closing my observatory roof
Defined Unpark Position - This is the position my telescope goes to at the start of any imaging night, and this is the position my initial Solve and Sync Blind is performed
The goal here would be to say at the start of the image sequence
Unpark to the defined position
Enable sidereal rate
Centre object (Which would perform a solve and sync to get the current position)
Perform the guider calibration (Or restore last calibration for pier mounted setups)
If you set up a start time in your sequence, it will automatically unpark the mount. If you tell it to ‘slew’ in the sequence, it will automatically slew to the first target. And, if you turn on ‘center’ in the sequence, it will also center the target.
PHD2 has options for calibration and saving calibrations. SGP would prefer that you have it calibrated already when you start, but you can force PHD2 to re-calibrate per target or have it re-use calibration (if you have an obs for instance).
But what it does not have the option of is enabling sidereal on the mount, this has to be done manually, so in order to have a sequence start, sidereal rate must be running, therefore the telescope is not parked. Or am I imissing a setting somewhere?
My mount (Gemini-2 Mi-250) starts tracking as soon as the mount is unparked and is commanded to slew. I would talk with the ASCOM developer and see if they can fix this. SGP is issuing the commands correctly.
Hi Simon. If you are using EQMOD then sidereal rate is automatically enabled when the mount is unparked and sent to a target. I’m assuming that unpark in SGP triggers the unpark in EQMOD which in turn would enable sidereal rate. Chris, would this sound about right? Simon, you could check with Chris (the other Chris) on the EQMOD site.
Did you run a sequence? Or did you just tell it from a target to ‘slew now’? If you run a sequence, SGP will tell the mount to unpark and. if you’ve selected it to slew, it will slew, and, if you’ve selected it to center, it will center the target.
One of the reasons for Park is to prevent inadvertent slews when, for instance, the observatory roof is closed. Attempts to move the mount when it’s parked will throw a parked exception.
UnPark removes this restriction and restores the tracking state.
