Some telescopes work with JNow, not J2000. As best I can tell, the Frame and Mosaic Wizard is returning J2000. An important example of such are telescopes being controlled by TheSkyX including the various paramounts such as my MyT.
I can use recentering, but there are times (for long involved reasons) that I don’t want to use plate solving and recentering.
It would be very nice if we could have the option of choosing between the two. If we had to choose just one, my vote would be JNow.
I know this has been requested before and I’m adding my voice.
