If your trying to line the guide scope up with the same Star as your camera, i used the moon the other night, made for a very quick alignment....

Use CCDCalc to work it out based on your focal length.

Use CCDCalc to work it out based on your focal length.

I have the fov fine, but its working out exactly where is goes in relation to the center as its (the guide prism center) 17.25mm from the center of the main chip.

Plate solve snaps from main scope and guider and work it out from that?

TSED70Q, iOptron Smart EQ pro, ASI-120MM, Finepix S5 pro.

I think i know how to work it out, the CCD chip center from the guide prism is

17.25

I need to work out the aps of the guide, and convert this with the 17.25mm.
