[Aavso-photometry] HD37605 run

[Brad Walter]

Started a run at 041226 03:26 UT. Clear but seeing poor at over 5" FWHM
for target star. Temperature fell fast after sundown from about 45d F at
17:00 local time to 28d F at 21:00. Pretty cold for Austin Texas. Air
mass 1.34 at start of run. 40 sec exposures through V filter on FSQ106
with SBIG ST7E NABG yields about 38000 ADU for brightest pixel of comp
86. Saturation roll off with this particular camera above 40,000 ADU is
too great for milli-mag accuracy.
