After a couple of dramas I worked this up from data collected at SPSP this year

Nod of the head to Logan and Marc for kind advice and a loan of a bhatimov mask following some focuser dramas (user issues).
35 subs @ 300 sec
AP900, FSQ106N, Canon 60Da
Interestingly darks not needed, just dithered heavily and used Bias. Not a patch on Colins recent very widefield one but happy with where this is at.
Thanks for looking
