  Many of the stars in the Universe are located in binary or multiple
  star system, where several stars orbit a common centre of gravity.

I spent some quality time on my balcony last night
with my old C8 and guests Mercury and Venus.
Venus is obvious. I've been routinely seeing it a couple
of hours before sunset, and have followed it this

.

Sunday night as I was closing up old B8, the foucer mount came loase and
came off the scope and yesterday because I sufered a bad case of joint pain
I mostly stayed in the trailer all day. Even today with the message I got
from another astromer who I can is only moving into an ...

I'm trying to enter Vesta into my old version of Starry Night.
Culled from the web, I got these numbers:
Mean Distance (a):  2.3607012339 (AU)
Eccentricity (e):  0.09035411

Any thoughts on the Celestron CG-5A 'Advanced Series' go-to mount?  I'm
an occasional & very amateur astronomer, don't plan to be any more than
that, and have no inclination toward astrophotography.  I have older C-5
and C-8  OTA's.

have 120mm refractor.
would this improve my system?

I had removed the mirror last night, this am I made the new set of holes,
cleaned the mirror and have during most of today worked on getting it in,
but because of what happened yesterday, I was wore out a lot too. So I would
do something and then rest. I had goten the mirror in ...

Here's a update for my November 2005 project to capture the shadow
cast by Venus...

I've never owned a fuzed quartz mirror before, do anyone here have one? if
so what are they like? this guy says this one is down to needinng 120grit
sandpaper, itsn't that the last step? 14inch for $200 seems good, it would
have to be a truss, but I wonder about it first.

First experiment to make a will the C14 of the astronomic association of
Cavezzo (Italy) in the use in high resolution!

What a strange little solar system we have going on!  The Astronomy Picture
of the Day (http://antwrp.gsfc.nasa.gov/apod/ap070528.html), reveals one
heck of a bizarre quirk on the Red Planet.  I want to think there is an
advanced civilization living beneath the surface that didn't ...

i want to know about how to make a program in DOS.
