Reprocessed by stacking with frames taken from 20th January 2010 unfiltered. A total of 40 frames stacked. Far less noise and more detail. Had to crop much closer though because of rotation stacking issues.
An experiment to see how this would come out taken with an f/15 Mak-Cass. Certainly not what you’re meant to use for this type of object. It means you can still actually see the trapezium.
7″ f/15 Mak-Cass, Canon EOS 350D 6m19s of subs 5s – 30s unguided.
