Here is my humble effort, far from perfect but should keep me happy until I can capture a better one.
It took a few tricks to get the dust to show itself, but when it did I was surprised at how much there was!
Same setup as always, Canon 350D (with cooler) and 85mm lens, chugging along on my wooden horse shoe tracking mount.
19x 8 minute subs (2.5hrs) with darks.
I hope you like it, I thought I'd better call it a day at my 20th revision
(fair dinkum) I'll probably do a repro tomorrow that'll turn out better.
Larger size Here.
Cheers
Jo
