Well done Dave! An EQ6 is so much easier to use for imaging than the EQ mount, and will be even more so than the dob driver.
The frustration lessens, and so you enjoy it more.
I've got the standard EQ6 with v2.something hand controller. You don't *need* the latest and greatest for planetary imaging. I don't even align the goto. I just manually slew to the planet and track. That's it.
I never drift aligned for the first 10 months either, just pointed south as accurately as possible (digital compass with magnetic deviation) and made rough adjustments until the planet stayed put for long enough at long focal lengths. I just used the hand-controller to re-center the planet when it drifts.
Having said that, now i'm doing deep-space imaging and drift alignment is crucial, I do now take the time to do it properly and it only takes me 10-20 minutes to get it very accurate. It's good for deep-space imaging, and also much nicer when the planet doesn't drift at all. It means you can read the forums while capturing an AVI
I use my DMK and an on-screen illuminated reticle to watch the star drift. Much easier than peering through an eyepiece and I don't run out of batteries!
