I took this last night (8/6/2010) in questionable seeing - the scintillation was terrible. Ended up with only using 2 minute subs the light pollution was pretty bad - all up 99x2 minutes (3h 18min) ISo 800 Cooled Canon 40D on the 127ED - all driven on the g11. Stacked in DSS and processed in Pixinsight 1.6. M20 AND M21 could have been better but it is my first from home
