Galileo, time
by Chuck Hards 22 Jan '02

22 Jan '02

I thought for sure that more people would have an opinion on where to scuttle the Galileo probe! Galileo is yesterday's news anymore, I suppose. On another matter, watching PBS recently, I noted that the designer of Mt. Rushmore allowed 3" extra material on the sculptures, to allow for 300,000 years of erosion. In other words, the sculpture will not acutually be finished for that lenght of time (assuming the erosion will be uniform, which I doubt). Even so, that is but the blink of an eye in terms of geologic (or cosmic) time....The show reinforced in my mind the notion that one day, the only remaining relics of mankind will be deep-space probes such as the Pioneers and Voyagers....everything here on earth is doomed to the slow but sure process of subduction, and eventual absorbtion & incineration by the elderly, red-giant stage sun. What we discard in the cold depths of interstellar space will be our only lasting legacy, enduring long after we have died out as a species. What's that, you say? We are not going to die out? OK, hold onto that thought if it makes you feel better. It's wrong, but hold onto it... Chuck __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!

I have read that when the Sun becomes a red giant it will push the Earth out to about Mars' orbit. When it finally blows off it's fuel and becomes a white dwarf, will all of the space junk orbitting the Earth become part of the nebula?

Galileo probe
by Chuck Hards 21 Jan '02

21 Jan '02

NASA plans to scuttle the Galileo orbiter next year, by plunging it into Jupiter's atmosphere. This is being planned to avoid a possible crash on Europa, which may contaminate that world and any possible life existing there. I'm thining that a crash into Io may be much more interesting, especially if "safe-mode" shutdowns can be overridden, allowing very high-resolution imagery of the surface. Contamination should not be an issue on Io. Opinions? -Chuck __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!

Darkroom question
by Patrick Wiggins 21 Jan '02

21 Jan '02

It occurs to me that there are more than a few astrophotographers on this list so I have a question for those folks. I've decided to get my long neglected Schmidt camera out of mothballs which means I'm also going to have to do the same for my darkroom. So, I ask you, should the walls of a darkroom, to be used for B&W photography, be white or black or something in between? Patrick :-)

Thanks for the note. It is nice to hear from people I know.

I'd have to credit it with my continued interest in astonomy, for without it I'd feel compelled to spend my time on a more rewarding hobby. I found it difficult to learn the sky through our light pollution when you can't always find the Big Dipper, but when I travelled to truly dark skies the sudden vision of so many stars compelled me to spend most of my available viewing time just trying to identify the constellations, which seemed to be camoflaged by the other stars. Getting a Telrad helped a lot, but here at home I find that even the light loss thru it, or background glare, can sometimes make a directly visable star impossible to find thru the finder. It is even worse now that my neighbor has replaced his two porch lights with two brighter ones (he was kind enough to give me two paper shopping bags to cover them). The Sky Commander isn't always perfect, though, either, but with careful alignment and an occasional "Realign on Object" function, it gets quite accurate. I have located objects with it that would have been far too dim to have identified with certainty without it. Previously, frustration level of using the telescope would have relegated it to a dust collector except for simple objects. I use it almost all the time except for quick observations of the larger objects, or for subsequent nights of tracking asteroids after having used it to find them in the first place. That's how I'm learning the sky. I've afixed the encoders on my Astrola equitorial mount with my 8" Cave from 1955. I've transported the unit at least ten times by car and camper without any problems with the encoders. The only weakness is that the pins and socket extend a bit beyond the case of the encoder where they can be bent in tranport. So far, this has not affected their function. I have used my laptop in unison with the Sky Commander two or three times with their free download planetarium software, but it adds a level of complexity that I haven't yet found to be of much value, perhaps due to the coarse resolution of the software. I have not yet used it with SkyMap Pro, but I think it may be more rewarding. There is an active SkyCommander mailing list on Yahoo where some very ardent fans willingly share their expertise. The archives hold discussions about the qualities of the SkyCommander compared to other DSC's. BTW - I've removed the original setting circles from the Astrola in order to mount the encoders. The original hour circle read backwards when I got the telescope several years ago. I had to remove it, flip it 180 degrees, and remount it on the shaft, even though it obviously wasn't designed to go on that way since the hub was not symmetrical and it was no longer close to the pointer. It made me wonder if I was either in the wrong hemisphere, or using the wrong hemisphere of my brain, but this scope was made and purchased in California. Any ideas on why this appeared to be backwards?

Those are cool images! I doubt the military minds though, remember when the shuttle had a damaged tile, the NASA could evaluate it from the ground. They can probably count rivets...

Digital Setting Circles
by Chuck Hards 17 Jan '02

While we're on the subject, can anyone recommend a commercial DSC package? Rich? If so, are installation kits available? (Dob, Eq., etc.) Im not interested in kits that require soldering or electronic component assembly. "Plug 'n Play" is preferred.
