I have been using Guide to get a visual star field for identifying asteroid Sagan. When I did a goto on my scope (accurately aligned) it went to a very close field but not quite that shown by Guide. The telescope's control software is showing the scope via Jnow coordinates and I think that Guide is showing via J2000 coords. Where can I change Guide over? I realised the error on the morning following the image run!

TIA
