So what do you do in this digital age with the excellent lenses you purchased over the years for your 35mm film camera? Well one thing is you can purchase an adapter from an Australian company that will mate your beautiful Minolta 250mm f/5.6 RF Rokkor-X mirror lens with your trusty Philips ToUcam Pro II Web camera. What you get from that is a very good Web cam with excellent optics for all sorts of uses — especially in getting "live" images from a telescope into a computer and, potentially, on to the Web.
Years ago I used the ToUcam to do a live Webcast of a total lunar eclipse. I'd connected it to my trusty Meade 390 telescope — a 1,000mm focal length scope. The result was nice imagery of only a portion of the lunar disk. I'd wanted the entire disk to show! With shorter focal lengths I can now image the entire face of the Moon or, with proper filtration, the Sun.
I did my first test imaging with the rig tonight at 7:22 PM with the Moon in its waxing gibbous phase. The image shown here (test imaage #5) was done with the Toshiba Microsoft Vista notebook computer, CoffeeCup Software's Webcam 4.0, the ToUcam and 250mm telephoto lens. Looks good! Not quite as sharp as I remember the Meade images, but not bad for a first try! Mount this rig to a telescope with a clock drive and we'll have something!
