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.

The partly eclipsed sun seen through a handheld solar filter.

The same method as to the left, but this time with the reflections in the filter showing the Maspalomas desert and hotels behind my back. 
Thus the background is image reversed, but the sun is correctly imaged.
