I have gone a bit polar alignment nutty...

Since learning how to do it with a camera + K3ccd tools, every night Im out I check it and make a few tiny tweaks... at the moment im getting 0.9 arcsec per minute drift... which is SFA! I did a week or so ago with the C11+2x barlow and 12mm ep.. got it to where I was happy with it, then plugged the webcam into the guide scope and it measured 1.2 arcsec a minute... thats pretty accurate, but it took me a bit over an hour. Using the guidescope + DBK + K3ccdtools 3 it took about 13 mins to get it to 0.9arc sec/min (after it copped a pretty solid knock out of alignment last week)

I dont just slap it down like I used to thats for sure... I got it so good that at 8400mm focal length I can keep jupiter in the CCD for about 2 hours.. Extreme!
