Godd work Markus. The next potential use for the 'modified' finderscope is as a guidescope. I cut about 20mm off the optical tube on one of these generic 8 x 50's (crude job using an angle grinder for absolote precision); removed the retaining ring on the objective before screwing it all together again; and then I turned down a bit of teflon I had into a simple eyepiece slider that slotted into the end of the optical tube and is held there by a couple of little self tappers. The other end accepts a 1.25 inch eyepiece (with a locking screw) or a web-cam. In my case I have used a Philips ToUCam 900 that now gives me a very adequate prime forcus guidescope that PHD and Guide Dog both recognise. Beats the hell out of spending a bucketload of good dollars on a bought one; more money to spend on other toys. Always a plus.
