V1209 Her

[coatesg]

A nice evening last night - dark and transparent - was able to get quite good data with relatively short exposures - here V1209 Her is between mag 13.4 and 14.1 - I started out with 3min exposures, reduced it to 2, and then (through a bit of an error) finished up with 1 min exposures. Even then, the error bounds are very reasonable. 350mm newt + ST2000XM, V filter.

I did also obseerve V488 Gem - on the other side of the mount, and lower in the sky over the houses, the tracking and seeing was not so good. Still usable data - just need a sequence from the AAVSO at the scale I work at (26x19 arcmin)
