How does Relativity account for the stability of the planetary orbits
if the speed of gravity is not inifinite, as in Newtonian Dynamics?

Does anyone have an overview of how big bodies can exist in the outer
Solar System?
Kuiper-belt objects are located between 30 and 50 AU. They were found
quite recently and one was as big as Quaoar, 1300 km across and

Bert, I wish this were April Fools, but it's not!

Given news.inidividual.net is charging for USENET newsgroup access, I was
wondering what other free options are available (if at all).  I use Tiscali
for my ISP, but specifically it does not include sci.astro.amateur which I
regularly access.  Any suggestions?  Thanks.

Is it true that our solar system is currently moving thru a Galactic cloud.
It can pose danger by destroying the Ozone layer.

Would anyone kindly tell me if RedShift 4 works no problem on XP/SP2?
It's been ok in Win98SE, but now I'd like to use it on a different
o.s.
Thanks for any clue.

wondering how the PC 'Atomic Clock' sync utility pgm from
worldtimeserver.com works?  How can it sync over the ethernet when
xmit/rcv times are random variables?  Or, can it only sync to nearest
second?  Anyone know the algorithm used?

Last night I decided to do a comparison between the effective transmission of
an IDAS filter and an infra-red blocker.  My wish was to identify the most
effective of these two filters for obtaining deeper sky images.  I am using a
12"LX200 classic and SXV-H9C camera and 10 minute ...

A couple of items from alt.com.freeware: my lawyer says I must say I have
no experience of either!

I am thinking of a design to enable me to put my telescope (LX10 currently)
out of our study skylight (velux window) when required. Hopefully this will
get it far enough away from any hot air escaping through the window, I could
also make some kind of a blind if required.

Sorry, I posted this on sci.astro.amatuer when I meant to do it here...
Hi all,
Took these full moon images with the Patrick Moore's 15" f6 Newt on Good
Friday.

Given the recent discussion on Porrima (whether it current nearing to
periastron can be seen/imaged and/or the double can be separated at
all or not) I gave it a go the other week. Due to it being very low in
the UK I had to filter for red (hence the potential resolution is
