Most parts of the equipment were bought used.

Tests and reviews of my astro equipment can be found at Astro equipmentreviews.

I live directly south of Vienna/Austria, therefore it is not easy to watch the sky. It takes me a 40 min. drive out of the city for a reasonable dark sky. Mostly I drive to Hohe Wand at Neunkirchen or to the Brentenriegel at Sieggraben or to the Wechsel at Grimmenstein.

I also use my computer for astronomy. Some programs I wrote by myself but mostly I use "TheSky 5".

Astronomical software I wrote by myself can be found at Software.
Practical tips for the hobby astronomy can be found at Astro tips.
Astrophotos I made by myself can be found at the Astrophotogallery.
A list of all published photos, pictures and articles can be found at Publicationes.
