The lens doesn't move at all any more, I removed everything from it, lenses, iris, focus mechanism, everything has come off. The only thing I wanted from the lens was the CPU.
But the lens body actually was a bonus since the inside of this lens is the exact same inner diameter of the focuser tube, so I just had to stick a tube and secure it on both sides, on the lens side the tube is permanently fixed and the on the focuser side I can remove with a 2mm allen key, in case I want to use the scope as a scope again. Also the inside of this lens is aluminium so it made a very solid setup, and the rubber grip from the zoom is the same diameter of the WO focuser. I guess I couldn't have found better even if I looked.
So, with all that I actually left the lens there like it is, although that wasn't my original idea. But I'm going back to that and I'm in the process of making another adapter, I'll use the CPU of this lens, but this time on a machined Teflon part, just being picky but I prefer the aesthetics of my new adapter

To allow metering on Nikon bodies. Cheaper Nikon bodies wont meter without a lens on, only a D200 or better will work without a CPU, and I want to be able to use the scope with any camera I own. This way I have the lens stuck at 300mm F/6.7, witch is what appears on the exif and what the camera thinks it's on.

Hi Fernando
Is it possible for you to show us a photographic breakdown on all the items you use from the ED80 to the DSLR and all the items inbetweeen you use or different variations or items you may use? I and others appreciate what you and Paul C have brought to the forum, i am being asked about the use of astroscopes and only know a very little based on yours and Paul C contributions, i am possibly tempted to try a setup?
Regards
Paul

Actually, no, sorry.
I wouldn't mind posting photos of the parts I changed or done, but I have none, or almost none, all I have is photos of the part I had machined for the dew-shield, and the old lenses striped down. Whenever I start building something a camera to photograph it is the last thing on my mind |8(|.
The only thing I can show are drawings of the new adapter and of the other parts I've made. Or maybe a photo of the new adapter but already finished, with the CPU built in.

More from my last outing with the ED80.
Just a Corn Bunting hanging around my Bee eater spot. This were all with either the Kenko Pro300 1.4 or 2x, but I don't remember witch is witch |=(|
I'm still working on the final changes on my ED80, after all is done will take a few shots of it dismantled and post everything here.
I'm also planing on making a comparison with my Ed80 against a unmodified unit, hope that works out so we all can see the differences some mods can do to these scopes.
