My effort from IISAC.
Please excuse the elongated stars, I found out during the next day during Greg Bradley's talk on Astrophotography that this would happen if shot longer than 90seconds unguided. These are 180.
Its pretty noisy as the iso is 1250 and pushed a bit in ACDCpro.
But, there it is. It worked and I'm happy.
Now, how much for a short tube ED80 and guide camera? Mmmmm
8 3 minute exposures (from 18) + 5 dark frames
GSO 6" Newtonian on HEQ5 unguided
Nikon D200 iso 1250 at prime focus
Cheers
