My Telescopes

Below you see my CG11, but first I want to introduce the 10"-Dobsobian I built over last winter (1996/97). I used it in May 1997 from La Palma, to make some last drawings of the vanishing Hale-Bopp and lots of galaxies.

More pictures and details of my Dobsonian and several  drawings of deep-sky-objects.

Most of my CCD images were made with the telescope shown below, a Celestron C11 (28cm=11-inch aperture, and 280cm=110-inch focal length), on a german equatorial mount (G11), manufactured by Losmandy.

Here you see my observation site (1997-2000), the telescope with the old CCD camera (LCCD14) attached and the controlling computer (in the grey box). A more detailed description of the C11  is available here  and one for the mount can be found here .

A self-made 8-inch F/4.5 Newtonian for CCD imaging had first light on May 3, 1999. One of the first targets was  supernova 1999bw in NGC3198. The telescope has since been used during my holidays in France (May 99) to image several faint objects.

Since summer 2002 I have my own observatory (see mey special page). The right image shows the currently (March 2003) installed  10" Newtonian  and the 6" Refractor, side by side. Located under the groundfloor is the warm room for several computers and myself.

Click to read more about my CCD cameras, the old  LcCCD14 and my modified  Cookbook -camera. Allthough these cameras are still available, most of the work is done with SBIG ST8-E and ST7-E cameras. In late 2003 developed Software allows to operate telescopes, cameras and image processing fully automatically. So the chance to detect new objects has come into reach.

Since summer 2005, my interests are focused on spectroscopy. I built several instruments since then.

In January 2007 a new heavy duty mount (WAM 6000) replaced my Losmandy G11. The 150mm refractor is not a real challenge for it.

My new 12" F/6 Newtonian mounted on WAM800CC. The leight weight carbon tubus  (4kg) maintains focus when temperature drops over night.

More about new technologies in modern, professional telescope construction can be found on my  special page.
You will find interesting facts and information about the Nordic Optical Telescope and the italian Galileo, both on La Palma island,  ESO´s Very Large Telescope and other giants, e.g. the 10 meter Keck-Telescopes on top of the 4500m high Mouna Kea vulcanoes of Hawaii.
