…it would be possible to view a postage stamp being held up at Castle Coch from the roof of the university’s physics building in the city centre around six miles away.

It will be used by undergraduate students studying astronomy and astrophysics and we are hoping that some of those students will take some amazing images through the telescope in the coming months. A new observatory website will pop up by 2009 to showcase our new toy, and I will give details here on Orbiting Frog when that happens.
