Jim did a major upgrade to his Tobin Cooler for our Canons which really kept the noise down on our images. So even though I only had time for 10 subs and I wasn't too sure how the image would come out, I think for 10 subs it's not too bad. I'll definitely have on my list when I can spend more time on these galaxies.
