I thought I would try and process another image today, from pier 7. I used 83 luminances, 101 reds, 45 greens and 51 blues all at 5 minutes exposure time. I did not use many of the subs provided, due to focussing issues with them, or because they were affected by cloud cover, but as you can see I had plenty of data. This equates to an imaging time of 23 hours and 20 minutes. M81 may be a bit on the bright side but it can always be adjusted... Have a good night everyone. Simon
