Distant Lights


by Thomas Henne


Looking to the sky in a clear night we can see thousands and thousands of stars.
But, invisible to the human eyes, there is something more between the stars - Distant galaxies, gas and dust clouds, star clusters - most of them are too dim to be observed, they can only made visible by photography.

Astrophotography is very complex and is completely different to normal daylight photography. It involves a lot of equipment, patience and knowledge on image processing. The photographed objects are extremely faint and therefore have to be exposed for a very long time to reveal their structures and colours. Exposure times of 20 hours or more over several nights are not uncommon. Due to earth rotation the telescope must constantly and evenly track the celestial objects. In the final step the images must be processed on a computer with special software.

Almost all of my images were taken from my home observatory in Zellerndorf, Lower Austria and processed by me.

I would like to invite you to browse through my website and enjoy my images of our universe.

Here are some of my, I think, most beautiful and remarkable images I have taken over the years:

For imaging I have used different cameras and telescopes.

Currently I use a 10" Newtonian Astrograph, different correctors and a Direct Drive Mount DDM60 from

and a CCD-camera from
