Baseball eclipse
by Patrick Wiggins 27 Oct '04

27 Oct '04

More on this in Monday's News but since there was some talk here a few days ago about recent baseball games, I thought I'd note that, weather permitting, those at Wednesday's world series game will be able to watch a total eclipse of the Moon while watching the game. >From what I've been able to dig up, this will be the first time that a total lunar eclipse has happened during a world series game. Patrick p.s. Just curious, but anyone know how the "world" series got it's name? Other than the US and Canada have any other countries ever participated?

Thanks Chuck. That make perfect sense.

It is much easier to balance. I have one question for Chuck. When you say the gears should be working uphill, do you mean towards the telescope side or towards the counterweight side?

I took out my refractor this morning and noticed my Starbeam red dot pointer is higher on the clamshell ring than the piggy-back bracket. All I have to do is move the piggy-back bracket where the Starbeam is mounted on the clamshell ring. Then I move the Starbeam to the right ride of the clamshell ring where the piggy-back bracket is. With the bracket nearly at the top of the clamshell ring, the scope should not be in the camera's viewfinder. Thanks to all that responded. Joe, one of the first things I do when I set up is balance the scope in RA then balance the scope in Dec. Otherwise, stars tend to trail when taking photos because of the movement of the scope.

Photo Album / Server Down
by Cynthia Blue 25 Oct '04

25 Oct '04

I'm back in town now, but the server is defintitely down. I believe some of the hardware is fried. So I'm going to have to see which part, and replace it. Load up a new OS, restore from backup, and then we should be running again. This is for the utahastronomy.com photo album. I may or may not be out of town again this weekend, depends on the weather. So It may be a couple weeks before we are back. I apologize for the delay. Should be fun setting up a new server though. If the CPU is fried, then I'll be buying a faster one, woot! :D I'm thinking a 120 Gig HD may be in order too. This list is through xmission, which is independend of the server though, so if it's slow, that's xmission's fault. ;) On a good note, Levi got another agility title. He he. Cyn

3-D Orion nebula

http://vis.sdsc.edu/research/orion_stereo.html Jim Gibson called our attention to this site some time ago; with the recent interest in winter objects I thought a re-post would be timely. Neat site, thanks again, Jim. All you have to do is cross your eyes and superimpose the images mentally. No glasses or stereo viewer needed, the images are already in the correct orientation for viewing. _______________________________ Do you Yahoo!?

I'm trying to find if this (that Meade bought Coronado) rumour is true before running it in News. Anyone else heard it? Patrick
