Ladislav,

As for silly, why has this site suddenly morphed into a political

Yes, it's a privilege to live in a nation so rich in freedom so valiantly protected.

It's just a shame we must be timid as to the abuses of our government. Scaled or fixed
taxes are essential to this protection and our on-going global marching.

I don't mind paying taxes; I just hate to see them so blatantly wasted. We've become a
nation of indulgence and entitlement.

Imagine if our great political system weren't so political; what deeds we could accomplish.

My two cents.

El Capitan is proving to be a very impressive mount indeed. Congrats Roland! Can't wait
to see one at the 2008 AIC (http://www.aicccd.com/) in San Jose? I'm not sure if this will
fit in the overhead.

I'll check with Delta.....

It would be very easy to change the face of politics and taxes in
this country:

1...Eliminate the withholding...all taxes would have to be paid on
April 15 by writing a check to the government for what you owe...

2...Then, all national elections would be held on the first Tuesday
following April 15...!

Gerald Sargent <sargentg@...>
 

In answer to the first question in the political sequence that followed
Roland detailed the precision of the 3600 goto and concluded with:
atmospheric dispersion, orthogonality of the optical tube,
flexure, mirror flop, time
errors in RA, etc. Those need to be modeled and compensated with
software.

Rolando
Can one infer (hope ?) that this implies that a software update is on the way
that includes modelling ? Gerald.

Re: 3600GTO questions

When did we start discussing politics on AP-GTO?

The income tax is the most evil, un-american concept we have ever
enacted in this country.

We do not need it.

Scale back spending to the year 2000 and you can eliminate it all
together.

I think the government spent plenty in the year 2000 don't you?

That's all I have to say about this.

Exoplanet WASP-10b in Pegasus (fresh discovery)

ayiomamitis
 

Dear group,

During the first week of Jun/2008, the WASP team announced two new exoplanets, namely
WASP-10b and WASP-14b. Both of these are significantly heavier than Jupiter and also
much more dense.

Although I was hesitatant last night about pursuing the first available transit of WASP-10b
for capture due to the low preingress altitude of the host star, I decided to pursue the
transit anyway so as get the experience and knowledge surrounding this relatively dim
host star (mag 12.70).

The results turned out much better than I expected and it is also interesting to note the
prediction for egress does not agree with last night's result, for it seems the total transit of
142 minutes should be greater.

For those interested, I kindly direct them to http://www.perseus.gr/Astro-Photometry-
WASP-10-20080828.htm .

There is another opportunity to capture this transit at the end of the month and with the
host star much higher in the sky. It will be interesting to see how my result then will
compare with last night's effort.

The discovery team makes reference to tidal effects and which most probably is
attributable to the presence of another exoplanet.

Anthony.

The shame of it all, the ones that can afford better get it before he gets in. Otherwise they won't either he will definitely take from the rich and give to the low life's. Mr George it's about time you turned over!

None of us can afford one until Barrack gets elected and gives us all

flexure, mirror flop, time
errors in RA, etc. Those need to be modeled and compensated with

Herb,

If you must go off-topic, can you at least spell the name correctly?
There is one "r" in Barack.

I guess I should feel blessed if I get even 50% of what was in my left

in that round trip through washington.
You guys should see what Europeans have to pay in taxes. We are truly lucky
to be living here in the US (versus some place like Zaire where you don't pay
any and are lucky to have a mud filled trail to travel on).
