Joe, I see it the same way and wondered the same thing even before reading your post. The ring is not parallel with the belts. I'm also wondering where the top of the planet disappeared to. Siegfried Jachmann Family History Network Comptroller 801-553-8881

Another Cave...
by David Bennett 21 Jan '03

Hi Folks, If you haven't figured out already I'm a bit of a Cave fanatic and have found another mirror for sale (10" f/5...I could make binoculars :-) on Astromart for some lucky soul: http://www.astromart.com/viewad.asp?cid=147528 This one even comes with a Cave 2.14" Secondary. Have a look!

Congrats to Jim Seargeant (long)

The following is a message from the SBIG list on yahoogroups. Congrats to Jim Seargeant for having his CCD work published in the SBIG catalog! ---- Message: 5 Date: Thu, 14 Nov 2002 22:28:12 -0000 From: "Michael Barber" <barber(a)sbig.com> Subject: Thank You! TO ALL SBIGers: I just wanted to thank the following people whose images were selected for our recent publications. I recently completed a first pass at an updated 2002 SBIG Catalog in PDF format (now available at our web site) and an image sampler on CD-ROM with the images organized by camera type. We get asked for these things a lot. Naturally, we selected what we feel are among the best images for each camera model from our image gallery and from recent submissions for both the catalog and sample image sections of the CD. In reviewing the images two things jump out at you. First is the amazing quality of the work being turned out and second is the sheer number of extremely talented SBIG users there are. We aren't just talking about a few. The catalog and sampler contain the works of literally dozens of you and we had to leave some out just because there wasn't enough room! And these are just the ones that made the last cut - what we consider to be among the best of the best. If you are on this list you are in very special company. If you aren't on the list yet it should still give you pause to consider the many new faces that have made it this far. Call it an SBIG Imagers Hall of Fame if you will, but I just wanted to acknowledge the following 53 people for their contributions to the catalog and sample image section as well as their images in our monthly image calendar: (In alphabetical order) Chris Anderson Jeff Ball David Barmore Adam Block Mark & Shauna Bolton Paul Borchardt Randy Brewer Tom Carrico Adrian Catterall, M.D. Mike Chapa Pin Chin, M.D. Roland Christen Antonio Cidadao Brian Colville Nuno Costa Robert Dalby Brad Ehrhorn Bernd Flach-Wilken Mike Fleenor John Gleason Ed Grafton Ray Gralak Mike Halderman Tony Hallas David Hanon Gary Hug Richard Jacobs, M.D. Gil Jones A. Julian Al Kelly Tan Wei Leong Steve Mandel William McLaughlin Marko Moilanen Stan Moore Mototsugu Motoki, M.D. Jonathan Murray Kunihiko Okano Don Parker Damian Peach Jim Riffle Gerry Samoylk Benoit Schillings Robert Schulz Chris Schur Jim Seargeant Gary Stevens Shoji Suzuki Loke Tan Sean Walker Peter Ward Volker Wendel Ron Wodaski If I missed anyone, and I am sure I did, please forgive me - and let me know. I am updating our web site and will add the sample images from the CD-ROM as I go along. The catalog is already there. Thanks to all of you and congratulations on your achievements. Amateur astronomy has certainly changed in the past 10 years. Regards, Michael Barber SBIG

And the subject of my talk will be a sneak preview of my upcoming doctoral thesis "A Scientific Study of Strategies for Post Menopausal Men and Women living Hunter-Gatherer Lifestyles in the Large Eurasian Cities of the Australian Outback".

Meeting tonight?

Since there was no mention of it in Patrick's news, I thought I'd check. Do we have a meeting tonight?

Re: Mirror grinding, anyone?

Hi Siegfried.: Sorry you couldn't reach me--I don't know what happened, but am glad to hear from you now. We've met in the dark a couple times over a Clave eyepiece in your beautiful Clark refractor, but I stay pretty low key so you probably don't remember (but how could I forget?) A presentation from me on telescope making would mostly highlight the concepts I've taken from others... I do think my telescopes are pretty and they do function very nicely, but they are a fusion of ideas from our own Chuck Hards (open structure), Phyllis Lang (rotating, balancing tube), Richard Berry (back plate, tube rings), Barry Peckham (minimalist groundboards), Bob Cook (velvet baffling), Dave Kriege (tube laminate concept), Bob Royce (cell design, thermal management), etc. My own small contributions (as far as I know) include an understanding of how to use lesser known commercial grades of countertop laminate to make a durable and colorful tube quickly, mounting a tube clamp ring on the front of the bearing box rather than inside the cradle, the use of acrylic craft paints to colorize the plywood edges to match the face veneers (and that was my wife's brilliant idea, actually ;^), my unique aesthetic approach, and an awareness of some of the techniques common to those who work and finish wood. The rest is just a lot of patience, hard work, and fussy attention to detail ;^). I do know from a lot of trial and error about dimensional requirements for balancing weight and damping time (at least with my own design), alternate bearing ideas, how to make effective use of a router (you could almost build an entire telescope with a router and a handful of shopmade jigs), and how different woods behave when being finished. And I'm still learning all the time ;^). Besides this discussion on the pending telescope making/glass grinding class, I am planning to build some EQ platforms pretty soon. Perhaps after everyone has a mirror and a dob, everyone can get together again and make some platforms for their creations later next year? Just a thought. Kind regards, Paul Stock

First off, please forgive if this message is HTML encoded--I'm crippled by AOL... I don't know if the mount designs for this mirror grinding class have been decided on already, but I previously decided that if this class was held again, I'd offer to any who might be interested use of my patterns, jigs and experience to assist in the construction of telescope mounts similar to those I make: http://blackknighttelescopes.com/BK_Black_Walnut_frames.htm I will say up front that making a wooden mount like this is a lot of work (easily dozens of hours, depending on how nice you want it), but I think it would be very rewarding to those willing to brave it. I can provide the following: - patterns to quickly and accurately route all the mount parts - training working with hardwood veneers (unless you want a maple or baltic birch mount, which is available pre-veneered) - instruction and assistance in finishing various types of wood - instruction on how to quickly make a very nice tube - helpful, friendly advice and access to some tools to help you with your own design - etc. I work from a smaller shop, so if invited, I would probably need to come to the hangar or to another location with more space for tools and room to work. It would also be good if I didn't need to bring every useful power tool, though I can certainly bring some of the more portable tools. It would be helpful if the cost of required bits, blades, etc. could be covered by those participating. I don't mean to crowd in on what might already be a well laid plan, so feel free to tell me if there is no interest. My personal schedule is pretty tight this winter, but if there is any interest at all in what I have to share, I'd love to squeeze in where I could. Finally, my design is best suited for 8" f/5 through f/7, 10" f/5 and f/6, and perhaps a 12.5" f/4.5 or f/5. You can probably go a bit longer for each aperture listed, but you lose the ability to shift the tube in the cradle to balance eyepieces, etc. and might need to make the mount a bit heavier to keep damping times low. Kind regards, Paul Stock

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.
