THE OBSERVATORY BUILDING

We started building our new observatory in the beginning of 2002 at a new site around 15 km's north of Aarhus. The outside was finished on the 20th. of July the same year. Here you can se it from the drive way.

THE TELESCOPE
In the observatory we have a 12.5 inch f:5 computer controlled Newtonian reflector .
We started building it in 1999 - we bought the optics and made the rest ourselves.
You can find more information about this project under "Articles in danish" further down on this page.

The Guide Scope
The guide scope is homebuild. The lens is a 80 mm fl:890 mm Apo-Nikkor. The refractor has build in motorfocus

The new photographic telescope - Oct. 2006
The Sky-Watcher telescope is a short focal length refractor. Aperture: 80 mm f/7.5 ED.
For remote focusing the telescope is equipped with a motor focus device - home build of course.
Some of the first images: M-31 The Moon

THE CCD CAMERA
August 20th 2004 we got our new Starlight XPress SXV H9 CCD camera. The H9 is a b/w camera featuring 1392 x 1040 pixels and operating with a pixel size of 6.4 um

ASTRO PHOTOGRAPHY

We do a lot of astro photography - until October 1997 it was entirely on photographic film - hypered TP2415 and using MWP-2 developer. In 1997 we finished building our Cookbook CCD camera. Link to building project article further down the page.
