Sorry for such a long time between my first post and my response... I had some vacation time and was deep in the wilderness of Wyoming Rocky Mountains (me, my two dogs, my small refractor and one very curious grizzly bear that had me sleeping with one eye open most of the time).
I have not personally used the Denk 21s on a 12 inch DOB but I will be doing some observing with local club members July 29 and 30th. One of our members has a 12 inch and another has a 20 inch dob so we will check them out in each and I will give you a update on what we find out.
