Jeez Darrin,
That first shot has nailed it for details, VERY good focus and astounding to see how much you have captured at that scale, well done!
Take a look at Mike Salway's tutorial on planetary processing
here which is great to cut your teeth on. I did.
Keep up the efforts, as Malcolm mentioned a quality barlow (might be a bit hard with the 40D, you'll probably need a 2" version.) really brings up the scale of the planet onto the chip.
Having said that, upon closer look of the second one, it aint half bad either! A top effort for a DSLR, normally this space is reserved for webcams and the PGR-fleas and planetary cams alike.
Keep at it. You are getting great results so far. We are certainly spoiled when it comes to the masters like Bird, Quark, Iceman, Paul Haese and John (Asimov) etc posting such astounding pictures ALL the time, so its encouraging to see an 8" scope doing so well.
You have inspired me to grab some data this long weekend on my new 8" with the Toucam and the 5x powermate.
Thanks!
Cheers
Chris
