Thanks Guy's, Mike are you using the LPI?
Surface detail would/could be better for two reasons A) conditions will always determine how much you or your imager sees. Some of us get lucky and be out at the right time. B) I didn't get the chance to stack nearly enough images. My PC must of cashed during most of those captures the longest was 103.
I use the Moons as a focus add, I would imagine it would be rather difficult with a Dob. Man I find hard trying to manual focus my sucker and it's on a EQ mount with drives... I would love an electronic focuser.... one day...
