the seeing was quite good: i measured less than 2" stars in some of the
frames

the problem was the wind.... kept screwing up my frames. that's why I moved
to globs with no filter. 5 minutes was too long, but with one minute
exposures I got to use about 1/4 of the frames I took

gotta build that observatory!

Richard,

that looks good considering the image scale. Nice round stars.
