I am just wondering what this should look like in SkyX. SB has produced a field of view indicator for the STXL but not an associated auto guider panel for the integrated guide camera in the filter wheel. I have tried using the STL indicator but found that the guide star selection is not accurate. My pointing is accurate but wondering if I am doing something wrong. Is the STXL guide camera positioned similarly to the STL?
The position is adjustable. I'd suggest using astrometry to determining ne the precise offset for your equipment.
Here's what mine looks like (FW8G guider). I set it up manually. Offset of guider is 26.95 armins from centre of imager frame (adjustable). Be aware that the image in the guider is reversed from what you see in TheSkyX chart.
