ISCO ULTRA STAR HIGH DEFINITION ANAMORPHIC Disassembly
Jim Chang replied to Francisquito's topic in Cameras
You need to separate the helicoid from the front glass housing. Just take out all the screws, and go from there. Soon you will figure it out. When you have the front glass housing & rear glass housing separately, then you have a lot of options to go from there, check our recent rehousing efforts on a similar 35mm scope: https://rapidotechnology.wordpress.com/2021/02/16/story-behind-developing-fvd-35np-fmj-35/ -
Finally, the tutorial about rehousing the B&L attachment I scope: https://rapidotechnology.wordpress.com/2021/02/16/story-behind-developing-fvd-35np-fmj-35/ Enjoy my friends.

You should adjust the rear glass's orientation, instead of removing the locking tab from the front glass housing. Best of luck.

Check the FVD-35A, which is designed for 35mm projection anamorphic scopes, like HIFI-2: https://www.rapidotechnology.com/products/front-variable-diopter/fvd-35a

HI, Racer5, PM me on facebook, will send you the manual of 16A, it has instructions to adjust the drag force yourself. Best, Jim Rapido

Let’s Talk About Larger 35mm Projection Scopes
Jim Chang replied to Caleb Genheimer's topic in Cameras
I have most of larger 35mm scopes, probably 20 of them. I like HIF-2, Bausch Lomb Attachment I, and Moller 63/2x, which are vintage look, the ISCO & Schneider are modern & cleaner looks. I am trying to shoot some tests of these scopes pairing with FVD-35A, stay tuned. https://www.rapidotechnology.com/products/front-variable-diopter/fvd-35a -
You don't need to modify it, just a little bit heavier than 16mm scopes. Pretty sharp lens.

Hi, Hank, Here is the independent encoder unit, which can be rail mounted on the side to record rotational information of the focus ring. I also provide two controller packages for order, package A & package B. package B is the one without the motor unit, and it's part 0009 at http://www.rapidotechnology.com/home I can modify the controller parameter to work with your Berkey motor, I can also provide an additional motor cable connector, which you can wire it to your Berkeley motor. Thanks. Jim Rapido
