And here's another from Monday night: This time with the focal reducer on the FSQ giving me f3.6 at 397mm fl.
Subs are 60 seconds @ iso 6400 and there is about 30 minutes worth. It was quite challenging to get a decent colour balance in this as there was an annoying purple-red cast - which was caused by the aurora :-).
Here's the high res version on
astrobin.
cheers again!
Andrew.
