More backfocus please

Posted By Luca Grella

Hi,
If your scope is a cassegrain then the backfocus is a function of the secondary mirror position.
If the secondary holder allows it, you can try to move the secondary a little closer
(just a few mm) to the primary. The backfocus will move a lot more than that
because of the mag factor.
I don't know what impact that would have on distortion and field curvature.
good luck

Oh, and I shouldn't fail to point out that the ultimate outcome in Iraq appears to be hugely positive.

Then why has Bush only now started to attack al Qaeda
and the talibans in Pakistan?
Maybe because he heard that from the Obama's speeches?
Or is it because it took him 7 years to figure that out?

Did you just pull your head out of the sand or what? Hell, you people (yes, I said that) are so hell-fired up against going into Iraq (which was sanctioned by the U.N.), yet you all want to INVADE Pakistan??



Jeffrey ,
my question was retorical.
Of course , nobody wants to bomb Pakistan.
And of course Obama did not call for a Pakistan invasion.
To go directly after al Qaeda and the talibans with the help of the allies (i.e. Pakistan), should have been done long ago;

The problem with the Iraq war is :whatever outcome you will get now
it will still be too costly in terms of human lifes.
Too many troops died and too many people died too, and most of them had absolutely nothing to do with 9/11.


Whoever will come after Bush (McCain or Obama) has already aknowledged
that the so called neo-con foreign policy has been a failure.
Nobody of the previous Bush administration has been , to the best of my knowledge, at the republican convention; this politically explains a lot.
I hope, for the best of the country, that the new foreign political course will have more wisdom than utopia.


my best regards

Do you reallly think that 650K job losses and 8.1% overall
unemployment rate is the result of the last 45 days policies?
Maybe Regan was right 30years ago, today he wouild be plain
wrong.

Right,
I made a question about unemployment.
I do not want to discuss the basis of America.
You did not give an answer but a political speech.
The question is:
Is the 650K lay offs the effect of the last 45 days of policy?

The report of 650k number refers to the month of February.
The stimulus bill has been signed on February 17 by the president.
Furthermore many companies have announced layoff plans starting on November 2008 up to June 2009.
Look at the data http://www.bls.gov/news.release/pdf/empsit.pdf
and you will see that unemployment has started ramping up
on 2008 from 5%.
As far as creating wealth goes we have already seen how that has been done: starting from fraudolent appraisals to inflate the housing market then going to derivatives , subprime mortgage backed securities,
and fooling the investors in a 250 billion investment fraud scheme(6 times the deficit of California) that will be repaid by tax$

That manager has not been honest to you. He probably was venting out some frustration. I have been in Europe for a long time and labour laws are very similar to US.
People can be laid off for shrinking bussiness, relocation of bussiness, redundancy
etc.. or can be very well fired for negligence.
Neatherland is one of the European leading economies with a very respectable 2% growth that has been attracting foreign investors for years.
In 2007 neatherlands economic growth was 3.5%, while US was only 0.6%.
It has (or had) very low unemployment, a surplus and healthcare guaranteed for everybody.
