Welcome to Owe Dahren´s Astronomy Page

I live in Kumla, in southern Sweden, 20 km south of Örebro, at 59° North, 15° East.

My main hobbies are astronomy and photography, and I´m an active member of Kumla Astronomi Klubb, a local amateur astronomy club.

This page contains my most recent astro photos and links to other pages with more images.

Partial solar eclipse in Maspalomas, Gran Canaria, March 29, 2006

Thus the background is image reversed, but the sun is correctly imaged.
