I took this on the Friday night/well technically Saturday morning of ISSAC2009 and while it is only 2 hours worth of imaging it has given me a goal to get many more hours of this next month when it is in the sky for longer. taken with a modded canon 20D, canon f2.8 200mm L lens ISO 800 and a stack of 3 minute shots. Entirely processed in Pixinsight - only resized in photoshop for here. the sky conditions were challenging - a clear but boiling atmosphere made auto guiding a challenge. Scintillation saw my earlier efforts of Pleiades a waste of time.
i will be doing several "Sidonio's" (ok for those that done know - reprocessing
) of this
by the way - I processed this under Duress of Mike Sidonio, RB, Fred V and a few others watching over my shoulder - they were pretty quiet - i must have done something wrong LOL
