Hi Folks, I've had a nice 10" RC-style Cass mirror set that has, in fits and starts, making its way to becoming a telescope. I've run into some issues that I find I really need help with. If there's someone who'd be willing to spend some time coaching me, I'd be most grateful. If someone has, or knows of a place to do some testing of Cassegrain mirrors that would be extra helpful. One of the main issues I'm struggling with is trying to determine the correct separation of the mirrors. I know that can be determined quite well with a Ronchi test, but I've been unsuccessful in achieving a test setup that even allows me to see the lines. At any rate, if anyone has some time or knows of some sources to check into (other than members of SLAS who I'll be trying to hit up as soon as they allow me to post to their list), I'd sure like to hear from you. John

Did a star party last night (solo) for a group of scouts up at Payson Lakes in a meadow near loop 'B' at about 8,000 feet (ideal). Anyone else observed from up there? The sky was fantastic last night, and it's just under an hour's drive from my home in Lindon. The star clouds in Sagittarius were especially lovely. /R

We are considering doing the Astronomy Merit Badge and are wondering whether someone from your club might be willing to come to our camp one evening with a telescope for the boys to look through. I don't know if that's something you do, but I found your club through the Clark Planetarium and thought I'd ask. Thanks, Bret Hicken
