Re: Should I use my BARADV for the upcoming lunar eclipse?

A note on tracking: a 15 second exposure is quite a long time unguided. Especially on the moon which doesn't travel at the sidereal rate. The lunar rate setting on APCC is only approximate since the lunar rate varies during the lunar cycle. And it's RA only so doesn't account for declination drift. So halving that to 8 seconds could be quite a good thing.
