NGC 2997 8 hours with Star Tools Help!

Hey all, I recently added more data to my NGC 2997. It is now 8 hours and ten minutes with a 110mm f6 refractor, five min subs calibrated.
I initially got some help with Star Tools from Ivo, the source himself!, and he was kind enough to write down a menu to help in processing, which I followed on this reprocessed with added data...
I also tried to eliminate the dead pixel columns with mixed success (I tried on the right only). First one is a crop to avoid these..
I wondered why they sprang up as I as dithering in nebulosity (small or medium dither/0.2 sec)
I never noticed them on the original set of subs (these were taken on four different nights) but they might have been there all along.
Anyway
8 hrs 10 x 300sec with QHY 8 OSC f6 110mm
Processed (thanks again Ivo!) StarTools after stacking and calibration in DSS.
I think this is my best effort yet (my efforts so far have been climbing up Mount Modest at the best of times!).
Cheers for looking
Graham
