My Dobsonian Telescope

Detailed pictures of the 10"-Dobsonian I built over last winter. I used it in May 1997 from La Palma to make some last drawings of the vanishing Hale-Bopp and lots of nebula, galaxies and one quasar, jpeg, 11k.

The adventure to bring such a telescope to La Palma is another story ...

The next 4 images show my Dobsonian on the 13th IIT in Kaernten, Austria. It was a great telescope party with many nice people and big scopes.

I list some improvements for Dobsonians on this page:

- digital setting circles, are offered by many companies. They make it easy to locale any object in the sky. Last September I could benefit from this equipment attached to a friends dob, when we observed 12mag comet C/1997 J2 (Meunier-Dupouy) without much trouble. Many people will vote against it because it is much harder to learn the sky with this kind of equipment.

- equatorial platforms. I haven't seen one yet. This hardware allows you to track for a certain time (something around 1 hour). That is interesting for people who want to take photographs or ccd-images of celestial objects.

- fully computerized Dobsonians. The leading man in this field is Mel Bartels. If you want to do it yourself, you must have some knowledge in computer hard- and software, in electronics and perhaps most difficult, in mechanical engineering.
