Are there any good hiking trails up there? I need to take advantage of that fresh air. Debbie

Today's NASA Briefing
by Patrick Wiggins 03 Feb '05

03 Feb '05

Two things of note out of today's briefing. 1) The briefer noted they have received 132 reports of found debris in CA, 130 in AZ and 9 in NM but that none had been confirmed. He made no mention of Utah. 2) The picture mentioned in the Aviation Week article was shown. Some of the media has been playing it up as being "hi resolution". Don't know that I'd call it hi-res but it does show the shape of the orbiter and maybe there's "something" with the left wing but the image is so pixcelated it's hard to say for sure. No doubt the picture will be all over the TV tonight.

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

Looks like another photo opportunity as it heads towards the Pleaides.

RE: [Utah-astronomy] f/4 or f/5? Why not try...
by Debbie 30 Aug '04

30 Aug '04

If I decide to upgrade, I'll think I'll go with the f/5 version. There is less of a central obstruction with the f/5 than the f/4.5. An f/4 has too much coma and is harder to collimate. The image size is a little bigger with the f/5 version. And the Paracorr is not necessary. For Dave Kriege, the f/5 is a "no brainer". I'm thinking about purchasing a trailer first before upgrading. I want to be able to view with my refractor and my reflector plus have room for sleeping bags and such. The Kolob Reservoir site is about an hour and twenty minutes from my house so I think it is wiser to sleep up there until morning. Debbie ps missed you up at Wolf Creek Pass. It was very cool and confortable up there.

f/4 or f/5? Why not try...
by David L Bennett 30 Aug '04

30 Aug '04

Why not go for a 16" f/16.5? See the mirror being offered at: http://cgi.ebay.com/ws/ eBayISAPI.dll?ViewItem&category=31745&item=5917131317&rd=1 Brent Watson can attest to the benefits of observing from 20 feet off of the ground. The seeing is always steadier from such heights. Those with vertigo will stay away so lines for your scope will be shorter. You can get away with a very small secondary obstruction too and collimation is a cinch. No need for the correction of Naglers or a Paracorr either. Of course you need a flatbed to transport both the tube, counterweight, and extension ladder. Remember, look with both eyes for best effect when viewing a first quarter moon from a dozen steps up the ladder. Those purple crescents make for a great trip! dlb

> What a perfect 'stocking stuffer' eh!? That's a ways off isn't it? I haven't backed over any nuns lately so my optimistic side is telling me that we could be in for a crap load of clear skies between now and Christmas. I'm pretty sure that somewhere in the world, there is a celebration of some type going on. I think I will purchase one of these little gadgets today in honor of such an occasion. Whatever it is. ;) Thanks for the link Daniel!

A 20" would give me a big performance boost over my 15". My friend Jim sold his 20" Starmaster and bought a 25" f/5. Everybody down here loved the 20" and was sorry to see it go. Most of the time we were only on the second step unless near the zenith. That Star Tracker is also nice too.
