Microsoft/Worldwide Telescope

Posted By Rod Mollise

I just downloaded this and played around a little- very slick!

From the AP:

WorldWide Telescope, developed by Microsoft's research arm, knits together images from the Hubble Space Telescope, the Chandra X-Ray Observatory Center, the Sloan Digital Sky Survey and others.

Computer users can browse through the galaxy on their own or take guided tours of different outer-space destinations developed by astronomers and academics.

The site lets users choose from a number of different telescopes and switch between different light wavelengths.

Let Hubble Die

Posted By Rod Mollise

Chad Braithwate said:

That got your attention wink

But seriously, perhaps we should have let Hubble die? It's a moot point now, the service mission will go forward soon. Setting aside the emotional attachment of the general public and the home state politics (Maryland's congressional delegation, where the STSI is HQ'd, led the charge for a repair mission in Congress), is the additional $1 billion cost worth the human and technical risks? A couple of points:

The bottom line? Shuttle missions WILL continue until the program's end in a few years whether the HST is serviced or not. The money can be spent either to service HST OR for the (IMHO) less worthy task of adding another wing onto the white elephant ISS.

The Hubble's capabilities are different from those of the JWST, and we might be very happy to still have the old gal, to have an optical space telescope of some kind, if something goes catastrophically wrong with the newun--which CANNOT be serviced.

Any high performance aircraft is a "death trap."

Aperture, Planetary Viewing, and Seeing

Posted By Rod Mollise

Alan French said:



I have yet to see a night where the smaller aperture revealed more planetary detail. There were always moments to minutes when the larger showed more detail than the smaller.

Same here...there is simply no doubt. Yes, under some conditions the planetary image in a smaller scope may be aesthetically more pleasing, but seeing almost ALWAYS settles down at least once in a while, and by the end of the evening, the large scope has shown far, far more than the smaller one.

Has anyone used these eyepieces?
What is the quality like compared to other EP's?

Brian

TeleVue? No. Worth the price? Most definitely!

circle t meade orthos

scott trehy said:

found a rare set of meade orthoscopics (japanese circle t)and was wondering if anyone knows how they stack up to the university optics orthos?thanks.

These Towa made eyepieces are pretty much indistinguishable from the UOs.

RE: Orion 9x50 Correct Image Finder Mount

Posted By Rod Mollise

Charles Solomon said:

I was given an Orion 9x50 corrected image finder without any mounting hardware. I have an 8" Meade telescope I was thinking about mounting it on. However, I don't know what kind of mount to get for it. Or, if possible, I could manufature something for it. Has anyone come across a similar situation and have any ideas what I could do? Does anyone have an Meade finder mounts that might work for this thing?

Thanks

Any 50mm finder work of the single ring variety will work. One of those Orion sells, for example.

The only limitation is that if you use a two ring finder mount, make sure the two rings are not too widely spaced.

Free LED Astronomy Flashlight!

Posted By Rod Mollise

Michael Tencza said:

That's right. Inside Kellogg's Frosted Miniwheat they are giving away an Indiana Jones plastic spoon illuminated by a red led. Take off the spoon end and you have an astronomical flashlight. It has a better pattern than my Orion led flashlight and best of all is free.

What the--?! I was gonna use that spoon to eat my grits at dawn!

Standalone Autoguider

Posted By Rod Mollise

Kerry Green said:

Hi all,

I'm looking for a standalone autoguiding system much like the SBIG ST-4. I cant seem to locate anything like that. I am willing to build the darn thing if i have to. I may just try that anyway. Anyone have thoughts?

Thanks,

-KDG

If by standalone, you mean "no computer," your are purty much outta luck unless you can find a used STV or ST4.

collimation

Posted By Rod Mollise

robert black said:

I recently moved my scope off the pier to take to a star party for the community to learn about astronomy. When I put it back on the pier it is out of collimation and I can't seem to get it back. The problem is no matter what screw I turn, I can't get the ring centred.
I have a 8" SCT LX90 w/bob's knobs. but my arms are not long enough to look into the eyepiece and turn the knobs at the same time.
I would sure appreciate any suggestions, thanks guys, bob

Not sure what you mean by "ring." Put Polaris in the field, and defocus slightly until you see a series of rings. Not so much that it looks like a great big donut. Adjust screws by small amounts, by tightening them, until the rings are concentric. One trick is to put the side of the star that is "squished" against the edge of the field and adjust the screw/screws that move it back to the center. Only adjust by tightening. Only when a screw is snug and you need to continue in the same direction should you loosen its opposite number(s). Do that and your scope will maintain collimation even after a road trip.
