After a few days away the first evening after my return was completely cloudless for a change so I decided to do a repeat session on NGC 5907. This time I managed to obtain 15 subs, the final image coming from the best 12. Despite the extra exposures any improvement on my previous image seems fairly minimal. Slightly better detail perhaps but a helpful excercise in discovering the best regime for my system. Details: 12x 7 minute exposures @ iso800 with CLS in DSS & CS2.
