Notes/ Conditions |
Conditions- Average seeing and transparency. Heavy dew
when taking the Lum on the 7th. Things were alittle fuzzy. I then had a
good night and added to already acquired the Lum. .Interesting to
note the faint red circular patch of emission to the lower R/H
corner. This appeared in a raw un-calibrated composite I originally did
with the RGB, I then removed flats, bias from all channels subs and this
curious object still remains. There's no information on this object. |
