Astronomy

 

For imaging the night sky, I use a Nikon D700 DSLR camera connected
to a Celestron CPC 1100 Telescope. When using a Hyperstar accessory, the telescope
essentially becomes a 560mm f2.0 lens when paired with the Nikon camera. Optionally,
the telescope can function as a 2800mm f10 lens.

The moon was aquired as a single fast exposure. The galaxies and nebula below were captured
by combining 8 - 64 images (typically 30 seconds exposure each) to increase signal to noise ratio on
these dimmer objects.

 

M45 - The Pleaides (Seven Sisters) - 435 Light Years away.

 

 

NGC 2024 - Horsehead Nebula and M42 - Orion's Nebula.
This picture was taken using a Nikon 80-200mm f2.8 lens with the camera
riding on top of the telescope



NGC 2024 - Close up of Horsehead Nebula.

 


M31 - Andromeda Galaxy - 2.5 million light years away.

 

 


M33 - The Triangulum Galaxy - 2.4 million light years away.

 

NGC 891 - An edge on spiral galaxy about 30 million light years distant.

 

 

NGC 891 - Closer up - This image made from 100 x 30 second exposures at f6.3 / ISO 25,600 on Nikon D700.


Interacting Galaxies M81 (left) and M82 (right).
M81 is believed to have a massive black hole in its center.

 


M51 - Whirlpool Galaxy and a companion galaxy on the left (NGC 5195).
These two interacting galaxies are estimated to be around 23 million light years away.

NGC 253 - Sculptor Galaxy - Estimated around 10 million light years away.

 


M42 - The Great Orion Nebula (bottom) and NGC 1977 - The Running Man Nebula (top left).
