First light new image train
I've been absent from here for a while - trying to get a new scope and camera train aligned and ready for the stars.
The scope is a custom 300mm f/7.9 RiDK from Officina Stellare. It is teamed with a Moravian G4-9000 camera for a plate scale of 1"/px, which is tuned for my dark sky site. Astrodon filters; DDM85A mount unguided.
Unfortunately, due to some timescale problems, the dark sky site went off-line for upgrading just when the scope arrived, so the working up has been in lovely suburban Melbourne (SQL 18 and poor transparency.)
The image train alignment is now very good but not yet as I'd like it.
I shot this image of M8 after my eyes failed me last night....
It is 3 x 10minute subs, Ha, calibrated but no flats. A rough backgroud extraction, and a histogram stretch is the only processing.
