Re: ReCal Procedure in APCC

Hi Mike,

As Roland wrote, the procedure is valid, but be careful.  The GoTo coordinates may have been precessed into JNow, while the star coordinates you read may be J2000.  

The safest and simplest is to use the Sync in MaximDL to sync on the star.  Be sure to sync on the target star.  If you simply press sync, it may sync on the centering coordinates which will mess you up.  The synced coordinates should be consistent with regard to epoch.  The driver and APCC will convert the sync command into a recal.
