Plate solving that includes the rotation angle

Hi all
it would be very useful to allow a target’s angle to be set, and to then have the plate solving to include rotation correction

This would support the following use cases

  • Precise positioning to place a guide star on the guiding chip
  • Orientating to align with an old data set
  • Framing that been established externally

Welcome Nicholas,

this is on todo list.

All the best


I have requested the same feature and, as Leo said, it is on the To Do list.

In the meantime, here is a workaround. At the beginning of your imaging session, open the OnTheFly panel and click Plate Solve Actual Coord. After the solve, in the monitor section, you will see within the solved coordinates a camera rotation angle. Compare this to your desired angle and rotate the camera by the necessary amount. Solve, rotate, and repeat until your camera angle is within the desired range.

Kind regards,
