• Pulse: Initial pulse size for calibration.
  • Iterations: Maximum number of iterations calibration should use per phase. It may use fewer (If max move is reached).
  • Max move: Maximum number of pixels the calibration should move. Once it exceeds this amount, it will finish the calibration phase. It may move less if max iterations is reached.
  • Two axis:  Check if you want the calibration process calibration in both RA & DEC. If unchecked, the calibration is only performed in RA. 
  • Auto square size: Automatically select the square size based on the selected star width.


Checkbox options

  1. Removes the effect of DEC backlash when calibrating guider.
  2. If checked, always re-calibrate when guiding is started. This is often not necessary when a good quality calibration has previously been done and the guide camera has not been rotated or re-installed.
  3. Store and attempt to reuse calibrations. This only works on opposite sides if the meridian if the pier-side can be automatically determined from your mount. The "Reset Guide on Slew" option above must be unchecked for this to be attempted.
  4. When re-using a calibration, reverse the DEC angle if the current pier side differs from the one at calibration. This only applies when re-using calibrations, The value you need is a property of your mount that should be restricted.
