interestingly I have processed Alan Meehan's Data just to see what the difference is, same camera type, different scopes - his is a meade Sn10".
Stacked in DeepSky Stacker, then saved into photoshop and saved as a 32 bit Tiff, then processed with PixInsight 1.56 - then resized for here in photoshop. i will note that i have calibrated my laptop monitor with Spider3Elite. So is there a difference....
