Stellina: Quasar 3C 273

[DrMike]

This was just more of a test and to satisfy my curiosity. Quite amazing really as it is 2.4 billion light years away, is the first quasar ever discovered, with a luminosity that is 4 trillion times that of the sun, and is apparently the most distant celestial object average (!) amateur astronomers are likely to see through their telescopes.

Anyway, sky conditions deteriorating ( as was I, long day!), 50s @10s subs.

If you pop a diffraction grating in front of the camera you can even measure the red shift as here in Patrick Moore's back garden back in 2005 using a prototype of the Star Analyser (bottom of the page)

EDIT: You would have to hack the Stellina though. Anyone doing that yet ?
