Hi Bill,
I have a question about coordinate systems in Guide9.
My mount is using Jnow natively, and so does CCD-Autopilot5. MaxImDL can also be switched to Jnow.
I would like to use Guide9 in that mode too, because positions can be off by a few arc minutes now.
In the Guide9 "settings-formats" menu I can choose between:
J2000
B1950
Mean of da... (last part illegible)
Apparent
Other___
Which one do I choose?
Thanks.
Best regards,
Albert van Duin
