Thanks very much everyone.
Hey Mike - it really isnt any bother at all when you can do unattended, automated data acquisition all night long from a static observatory, while you are tucked up in bed! Obviously, if you had to trek out to a dark site, you would not be getting 50 hours on anything.
This is the FSQ106 - Just cropped.
Paul - I did do this with the RC, full SHO palette with 25 hours SII as it has almost no emission in this band.
More exposure to come.......
