No idea on the "heat of evaporation" of the neutronium, but the beta decay
of neutrons yields a maximum beta energy of .782 MeV (generally less, though
, since the anti-neutrino carries away some energy).

Tim,
  I owned a C-8 with the fork mount, currently own a C-14, and have used
the SP mounts.  I do almost nothing but astrophotography, the major failure
of the SP mount is in it's stability.  The main body of the scope is supported
in the center (aprox) of the tube.  This support runs to a plate which is
supported at only ONE end.  This can cause the dreaded "TUNING FORK" syndrome.
 
  You touch the scope and it takes quite a while for the vibrations to die
down.  I have not owned an SP mount, however, just seeing this kept me
from purchasing it.  Celestron may have changed this in the last few years
so look at a current SP mount to be sure.  
 
  Regarding the PEC type of drive, you may want to call CElestron on that one.
It would not surprise me to see after market PEC type drives coming out soon.
As a matter of fact, I am surprised one or two have not come out already.

Since neutrons are 'radioactive', with a half life of ca 13 minutes, 
and with a decay energy of about 2 Mev, the 1 cc mass suddenly freed
of restraint would explode.  The gravitational binding energy of so
small a mass (10e9 tons or so) will not prevent this.

Last night at 8pm PST from San Francisco I saw a satellite heading northward
from Sagittarius to Cygnus. I tried to time it's travel and catch it on the
next orbit but was unsucessful.

Are there any public domain programs to calculate when and where
to sight the larger and more visable sattelites? Or are the orbits so 
obvious that it only takes a FAQ?

     I have the feeling that this will be a poorly formed question, but I'll
try anyway.  At the time of the Big Bang or very shortly thereafter (say before
the inflationary epoch), our universe was some size.  (Supplementary question:
If it is open now, was it open/infinite in size back then too?)

     Now, the question is this.  Was the size of the universe determined by the
extent of the spacetime or by the extent of the mass-energy within it?  Does
it make any sense to consider the gravitational effects outside of the defining
spacetime?  Would the universe even then have to be expanding at the speed of 
light for it to `contain' the graviton field?  If these questions are really
badly posed, what exactly did determine the `size' of the universe, and was the
mass-energy evenly distributed within it?

     This whole line of thinking arose because an acquaintance hypothesized
that the mass-energy of the Big Bang expanded into a region of low energy
filled only by gravitons.  The temperature difference between the expansion
front and the `interior' was the source for the current flows that powered the
plasma cosmology models.  Of course he misunderstood the Big Bang to be a
mass-energy explosion rather than a spacetime explosion, but his idea still
got me thinking and questioning.

     So, any helpful hints?

So, given that this is a simple physical problem (adjusting satellite
orbits) how much energy will be required to do it in 100, 1000, 10,000,
100,000 or 1,000,000 years?  Just wondering how many Saturn V's it
will take. :-)

Hello,
	I'm looking for information concerning PhD programs in astronomy
or astrophysics for the fall of 1993.
	I am currently attending the University of Mississippi and will
be receiving an MS in High Energy Physics in May.  For the last three 
years I have been doing research with the E791/TPL collaboration 
at Fermilab and am currently working on a paper on the A dependence
of D0 charmed particles.  I have worked extensively on the astronomy
classes here at UM and did a great deal of work writing the lab manual that 
is now in use.  I have some experience in both computer hardware and software,
and detector hardware. 
	I am looking for an astronomy program that 
has some cosmology and high energy astro, and teaching positions 
(either lecture or lab).  Any information regarding such programs would be 
very useful.  Thanks in advance.

Thanks to all who responded to my request for information on low-cost,
beginners telescopes.  I have learned a lot in the past few days.

Just wanted to tap your brains for a bit more information.  I have heard
from a couple salesmen and read in the book _The Amateur Astromoner's Handbook_
that the low-end "serious" telescopes begin at 3" refractors and 6" mirrors.
However others have told me that a 4.5" mirror is superior to a 3" refractor,
at least for deep space viewing.  As I am looking at several options in the 
$300 range (and size is a restriction ... can't go with anything as bulky as
a 6" or 8" mirror), this becomes a vital data point.  I'm leaning toward the
reflector but as I have heard multiple negative comments about this size,
along with those which seem to think an 80mm refractor is superior to the 
4.5" mirror, I'm a bit confused.  I do like the refractor's lower maintenance
but don't want to pay an extra $70-80 to get something which may (or may not
depending on whom I'm talking to) have less capability.

Also, hopefully this may be of interest to someone out there, I have found
wildly deviating opinions of the Vixen line.  Ranging from one dealer saying
he would never carry that garbage, to a salesperson at Orion claiming the
Vixen 4.5" was both better and cheaper than the Orion 4.5".  He and another
sci.astro subscriber raved about Vixen's price/performance for the beginner.
Another surprising admission by the Orion rep was that their $299 60mm was
"optically the same" as the Meade 290, which can be had for $209 elsewhere.
He did point out the advantage of having a better, larger equatorial mount
than the Meade's and the 1.25" eyepiece vs the 0.965" (I believe Meade's
new 60mm goes with 1.25").  I was surprised by Orion being priced higher
than both Vixen & Meade but claiming few superiorities.

So in summary I have two questions:

A) 4.5" mirror vs 80mm or 90mm refractor.  Roughly the same?  Or does one
   have a clear superiority (in non-serious amateur applications with
   little to no photography concerns) in viewing.

B) Is Vixen a line to be avoided or is there little difference between them
   and Meade or Orion at this price point ($300-$350)?

Dana Bunner

PS  Thanks in part to your comments, I did decide not to go with the Edmunds
3" mirror & 450mm f.l., after reading a couple books, I decided there was 
too much out there I'd like to see and this scope would never let me do it.
