The biggest problem component is the beamsplitter. Can be pricey and hard to find. You want to use the 2-prism variety to avoid a double reflection, such as what you'd get with a semi-transparent mirror. Plans? You engnineer and draw it up yourself! We can get-together off-list if you're serious. Remember these won't work on most Newtonians. C. --- Kim Hyatt <khyatt@smithlayton.com> wrote:
