Last Tuesday night, I had very steady seeing and was able to view the shadow transit of Io across the neb.THe shadow was dark and sharp like a hole drilled into jupiter, a large red barge follwed the shadow with a bay and accompanying festoons, the seb was very calm just a few rifts,I used a #11 filter yellow-green to tame the C.A. of my 6" achro, best mag was 200x.
