About Derotation, Zenith angle and Epochs


Derotation is an integral part of our software, permitting long exposures of the targets.

As for the epoch, it's J2000, and then the software does the job.

The maximum angle is 85°, however, we recommend staying under 80°. Please don't observe near the Zenith, 20° would be the lowest.
