Astronomy nebula

The orion nebula region as captured from my backyard in Austin, Texas last Saturday night. I had been waiting for that perfect moonless night, free of clouds, but it just wasn't happening. The moon was 2/3 full and about 20 degrees away. I couldn't run very long exposures or high iso, but still I think this is my best effort so far. Still a work in progress, but getting there. Imaged with a CLS_CCD filtered canon 7D and 100-400mm lens at 400mm riding piggy back on Meade 8" LX200 classic…

The Butterfly Nebulae Captured by Hubble

Messier 57 - The Ring Nebula Credit: NASA/ESA HST, Spitzer ST, Giuseppe Donatiello RA: 283,387° Dec: 33,026 The Ring Nebula (Messier 57 or NGC 6720) is a planetary nebula in Lyra and it is illuminated by a central white dwarf or planetary nebula nucleus (PNN) of 15.75 visual magnitude. All the interior parts of this nebula have a blue-green tinge that is caused by the doubly ionized oxygen emission lines at 495.7 and 500.7 nm. In the outer region of the ring, part of the reddish hue is…

I attached a DSLR camera to a giant refractor telescope to photograph the Orion Nebula. Here are my early results using the William Optics Fluorostar 132.

Nebula IC 63 - aka the "ghost" of the constellation Cassiopeia - is slowly dissipating under the influence of ionizing ultraviolet radiation from a hot, luminous variable star known as Gamma Cas.

Earth is part of the Solar System, which is in itself a part of the Milky Way Galaxy. This Galaxy is among the group that compose the Virgo Supercluster, one of many who are supposed to construct the Universe.

This one is a composite of 2.5 hours of H-alpha from my QHY9 CCD and 2 hours of RGB from my modified Canon XSi DSLR. Both through my William Optics 66mm triplet at f5.6. They didn't line up perfectly, but if you don't look to closely it's a reasonably nice blend of nebulosity from the h-alpha data and star colours from the RGB data. Framed it just for kicks.
