Ahh, Sbig STF. I had an ST8300 mono for a while a year or 2 back.
All clear tonight, all night, so I got the rest of the data plus some RGB and flats as well. Time to change the scope and move on
Before this capture I installed the new ascom driver for the SX wheel.
It appears that in that process the S2 and O3 slots got switched.
Shooting flats has proved it, so the first image is arse about.
The core should be blue like this one.
A Sinodio is pending
