I want to clarify the new JNow feature in the SGP beta. As I understand it, even with a JNow mount, SGP is J2000 internally. So I gather that means when I enter the RA/ DEC for an object in SGP I should be using J2000 coordinates and SGP will translate that to JNow for slewing if it is a JNow mount. Is that correct? In that case, should I also have the plate solver set to JNow? Or, should it be J2000 since that is what SGP is using?
On the other hand, if I have a J2000 mount, might it be appropriate to enter JNOW coordinates in SGP for better slewing accuracy? If so, should the plate solver be set to JNow?
