The one thing I always double check before venturing out is to make sure I have my auto focus chip and T ring. Hand assembled by Clinton and I will be forever grateful for this vital piece of equipment. It's a toss up between the T ring and Clinton's old modded 20D as to my best piece of astro equipment.
I believe the one from Canada and the ones on Ebay are a bit hit and miss. Bryan (astroturf) has an Ebay version and it is not as functional as my one from Clinton.
To me there is nothing quite the like the sweet sound of "beep beep" when you hit that sweet focus spot. Now all I have to do is master polar alignment and post processing and who knows I might even post an image
