adapter for using old camera objectives with Vesta 675SC
Old camera objectives have advantage of relatively long focal length and low focal ratio (about 1:2). They can be used successfully for astrophotography in conjuction with modificated Vesta 675SC webcam. I have two old objectives from old 35mm camera (not functional yet). So they are cheap pieces of astro-optics for me. Here are their parameters:
Both objectives have the same bayonet gripping. As I am an old radio-amateur, I decided to use double-sided printed circuit board (cuprextit) plate for manufacturing the adapter for webcam. The whole unit is soldered. The bayonet gripping is hold by 2 U-profiles wich are screwed to adapter body. The construction of whole unit is evident from the following pictures. (Click the picture to see it larger.)
I plan to paint the whole unit with black color. But at first I have to do some tests with the adapter.
