Keyhole from 10 Chain Hill Obs
Didn't get much data on this one, had to snatch subs out of sucker holes.
All up it's around 21 minutes of exposure, 20 sec subs, at ISO 1600.
It's a pretty heavy crop as you can tell.
scope - 8" newt
camera- Canon 20d
mount - Mini Tower
stacked in DSS, processed in CS3 and Paint Shop Pro.
