Hi SGP team,
With off-axis guiding configurations, it is often necessary to calibrate PHD2 on a star close to the meridian before launching the sequence, especially if the chosen target is close to the pole. This is even part of best practices:
Get a good calibration, then re use it
- Within +/ 20 degrees of celestial equator (Dec=0)
- Within an hour of celestial meridian
My suggestion for improvement is to propose an option in the autoguide tab, where the user could choose to launch the calibration on selected coordinates before launching the sequence itself.
Of course, this calibration will have to be done after the rotation step.
