In the Connect Equipment window, select your Rotator and connect. Once you do that, PHD2 will automatically adjust calibration for the rotator angle, so step 4 is not needed.
The Reversed checkbox is for telling phd2 whether the angles reported by the rotator need to be reversed due to the optics flipping the image relative to the sky. To determine whether you need this setting:
- calibrate and start guiding
- stop guiding
- move the rotator a good amount, say 90 degrees
- start guiding
Guiding should be good after the rotation. If not, you probably need to check the “Reversed” option (set it and forget it … it won’t change unless you switch to a new scope.)
Before attempting a meridian flip with the rotator, you should make sure meridian flip is working without the rotator. You’ll need to be connected to an ASCOM mount, or, if you are using an ST-4 connection to the mount, use the ASCOM driver for the Aux Mount.
- start guiding near the meridian
- stop guiding
- flip the mount
- start guiding (same star or different star)
Guiding should be good after the flip. If not, try the option “Reverse dec output after meridian flip” on the Mount tab in the Brain. Some mounts require this, some do not.
Once you have confirmed that both rotation and meridian flip are working independently, you can try them together with your test procedure (excluding step 4).
You’ll almost certainly want to use the “Auto restore calibration” option in phd2 (global tab of brain); if things are working as expected, you will not need to recalibrate regardless of rotator angle or side of pier.
