Re: AP-1200 pointing and guiding data
Adrian Catterall <Catterall@...>
Pointing depends on orthoganility of your OTA on the mount and polar
alignment to name but a few, but the accuracy can be very good indeed,
such that an object is on the chip every time.
Periodic error is very low at 4 arc secs peak to peak for my AP1200. You
can see some results from my Web page quoted below..
