I know that HN isn't big on pretty photos.. But these are really pretty - and I certainly learnt from the descriptions (THe asteroid collision and the 3 trillion kilometre collapsing red giant).
Does anyone know what type of gear you need to take a photo of the sun like that? I can't imagine it's good for the sensors of my SLR.

To take photos like the image of the Sun in that article you need a telescope coupled with a Hydrogen Alpha filter, mounted to your SLR body. Hydrogen Alpha filters are rather expensive, unfortunately.

The spectacular Horsehead Nebula is almost lost in there due to the scale. The Orion Nebula: having a hard time locating it due to all the gases covering the pic.
