Paul, It's great to hear from you. I have tried contacting you through your website before. I for one would love to see your facilities and be appreciative of any advice and help you can share. Would you also consider speaking at an upcoming meeting? Actually next year that won't be for me to schedule but I think Dave would go along with that. Siegfried Lame Duck President

I am interested as well - I have the same question about cost, too. I do know the ballpark price from newport glass and williambell's catalog for the kit, but have not researched the materials past the glass and grit. One way or another I am going to build a scope, - doing so in a social environment like this class is exactly what I need. Kris Jones >>> crrjr70(a)yahoo.com 11/23/02 22:05 PM >>> Hey Brent, Although I have always been interested in building my own scope, I doubt I will have the funds to participate in this class. Just for the sake of knowing though, could you give me a ball park figure of what a completed scope would cost? Thanks, in advance.

Does the loose nut have a name? Siegfried I have a bug up my butt to grind a 4.25" schiefspiegler. What do you think? I'd be starting with about 180 grit. I have a couple of old plate glass pieces. I wanted to see if Vaughn has some cervitt or zerodur or other low expansion glass.

Leonids

Here's a page from Grand Junction's National Weather Service's site I found while checking the local forecasts for potential observing sites: http://www.crh.noaa.gov/gjt/leonid.htm From what I've seen so far from the National Weather Service and the Weather Channel .com the best outlook for both clear skies and temp is South and West...somewhere like St. George, Las Vegas, Death Valley. Less clear and colder near Delta/Filmore/Torrey/Moab/Mexican Hat. Please let me know if you'd like to find out where our little caravan ends up traveling on Monday. We're thinking of driving somewhere Monday afternoon, checking in at a local motel, going out for the night, coming back and sleeping for a bit before coming back Tuesday. I'll make sure and send out an email right before we head off letting you know our destination. Praise be to the Clear Sky Gods! Dave Bennett dlbennett(a)mac.com

Brent, I would be interested in the class. Using the same logic you have, I thought the winter would be a good time to give this a try. I have 2 blanks that I bought from Dan Cassaro off the net, but they are not the sizes you have indicated below. Mine are 8" and 16". Would it be acceptable for me to attend the class working on one of these. Each have been pre-cut to F7 and F4.8 respectively. If not, I would still like to attend and grind a 10 or 12 inch mirror as you outlined below. I need the experience as I have never tried grinding my own mirror.

I went down to Parowan Gap. At 8:55pm I saw a bright green bolide. It came in just south of Cassiopia. The interesting thing was that it appeared to hit a cloud bank. Just as it reached the cloud bank, it lurched, a little bit broke off and the main meteor continued under the cloud cover. I am not sure this was possible so it may have just been my viewing angle. I eventually went to bed and woke up at 2am. I thought they put on a good show. I counted bursts of 10 or more a second. I also noticed that most of what I saw was looking right at Leo. There were a lot of short bright meteors right near the radiant. The longer ones that I saw were going toward Canis Major. At around 3:50 the clouds got pretty thick. At about 4:30 I went back to bed. I know last year I saw more meteors, but that was without the moon. I think this year may have exceeded last year if we could have seen the dim meteors bouncing all the way across the sky. It was definitly worth the drive to the south. How was St. George? I couldn't leave early enought to get all the way down there.

Hi folks, I got up at 0200 and watched from Farmington. I didn't yawn till dawn like Joe. I saw three in an hour and went to bed when some clouds rolled in. I did log onto NASA TV online, which was doing a special Leonids broadcast, and it was more interesting, and a lot warmer, than looking through thin clouds at the near full moon. I sure am glad I went out to Little Sahara last year! Bob St. Marie

I envy Ron Jones and crew who got out of the city lights. I guess it is really dark out past Aragonite?
