Description

Finally got into the Dome with a somewhat clear sky last night, though seeing deteriorated noticeably after about 2330. But I was able to employ my dual Borg 55/ASI 2600MM image trains to gather data in all three NB channels. Processed these and used David's HSO formula to combine them.
