Morning All
I have just installed CDC on my computer and was getting 'acquainted'
with it for a few days when we had a power failure.
Before the failure I was able to bring up info on any object by clicking

Titan's a topical subject [well two weeks ago!] and just been playing
with my spectrogram taken Jan 23 via the 30cm SCT+grating+ Canon 300D

How well do Celestron SCT's hold collimation typically?  Do they require
frequent re-collimating, if transported and used gently, or is collimation a
once-every-few-months sort of thing?
Thanks!!

Just wondering, in Quantum computing, how fast does information travel
between entangled particles? I would imagine it's 'c' but I can't
currently see why (if it wasn't 'c' then I guess it'd be more
common knowledge as the implication is that it'd be instant and that

Date:       Thursday evening, 27-Jan-2005
Location:   Backyard, Palm Springs, California
Equipment:  Tele Vue 76 (3" f/6.3) refractor
Short backyard observing session with the TV76. The moon a few day

I'm looking for a small scope to use on the moon and planets, assuming

the Mak-Cass?
cheers

I went to the Photonics West SPIE convention this past week in San Jose
CA.  There must have been well over 1000 optics companies in the
exhibition hall, an incredible turnout.  I visited all I could in the
time I had, but stopped the longest at Elcan's exhibit, as they were

Hi All, I am renovating a wide angle eyepiece system and found that
the cement between one of the achromats had developed many bubbles. I
soaked the lens in acetone for a couple of days and succeeded in
dissolving the old cement. Could anyone tell me what kind of cement to

Believe it or not A. Jaegers Optics is back in business after an absence of 20
years!  The items they are selling on their website appear to be the same items
they were selling back in the 60's, including the old Edmund type equatorial
mounts and clock drives.       They are located ...

   Anyone use a laptop in their observatory or outside?  Do you have any
problems doing this?  Which laptop computer would you recommend?  A
Panasonic Tuff-book would be nice but are rather expensive.  Are there good
alternatives?

I was shocked!  Usually in the winter the seeing is terrible,
owing to heat rising off structures, turbulent atmosphere, etc.
But, last night it was terrific!  Finally had some decent views
of the Moon and Jupiter.  

Thanks to the many people made kind remarks and sage suggestions about
my first through-the-telescope deep-sky images, made on January 27 and
28. It's human nature; I couldn't just let it go. I revisited the M42
image several times in Photoshop, and I have posted my third "final"

...what would we see and how would it affect us?
Thank you

I've found an archive for the Messier data in France, but what happened
to seds.org?

Hi all...
As usual, the choices are abundantly confusing....
Any opinions on the best camera choice under $500 for moon pictures?  I want
sharp images.
