The images coming from BSM_S4 are beautiful: sharp, with good tracking, and lots of pinpoint stars. Unfortunately, that's not so great for bright targets like U Mon. The current B, V, SR and I should be drastically reduced by at least a factor of 5 to avoid saturating U Mon and all of the comps brighter than 9th mag. It looks like exposures of 10, 2, 1 and 1 seconds for B, V, SR and I would be appropriate. Given the short exposures, it would be good if I could get 4 or 5 in each filter to reduce scintillation effects. Thanks!
