I like the cobweb. 

[Clive]

I am a soft touch for star clusters, nebulae and galaxies.  I second Simon.

I quite liked the brightness temperature map... but is def one for the geeks... just in case you were worried: Brightness temperature is the temperature at which a black body in thermal equilibrium with its surroundings would have to be to duplicate the observed intensity of a grey body object at a frequency ν. This concept is extensively used in radio astronomy and planetary science. (I can't beat the explanation of wiki this time; http://en.wikipedia.org/wiki/Brightness_temperature)

I suspect this thread is about to degenerate in 3...2...1...

[Rodders]

Am I in time for the 'Chocolate' jokes?   

[Clive]

I was thinking more in the line of hot black bodies.

I'll send you a Zulu, Clive.

[Rik]

Is a Zulu Clive something like a Zulu Tango?

[Simon]

You'll have to tell us what a Zulu Tango is first.

[Rik]

Clive will explain. 

[Simon]

A Zulu with orange hair?

[Rik]

A little, maybe. Or someone whose dancing ends on the cutting room floor.

[Clive]

The Zulu tango was before my time Rik.  Sounds a fascinating dance!
