This would be a great starting point for my own design. I've got one of those huge monster dobsonians (16" truss type by Orion) It uses 2" eyepieces that I love using. It would be cool if I could rotate them about rather than fumble around in the dark trying to switch them. Its easier to start with other people's creations rather than working with a vacuum. :-) Whether I get something built and working nicely before the July/August Nebraska Star Party may be another matter, but it is great looking at this creation of yours.

Thanks, I hope that this design will inspire you to come up with a solution for your 2" eyepieces. I made this one even though I'm not a visual observer myself. Just for fun to see if it was even possible ;-) If you succeed in your effort please let me know. I'm very interested. Also, if you have any questions regarding this design please let me know.
