Solar Images from Swiss Astronomy Amateur

Blogged by Xiao Sun on December 19, 2008 and tagged with Sample Images, Sun.

We recently received two fascinating images of the Sun from Christoph Schaefer. Along with these pictures, he also sent us a short article that briefs how he did it with his DMK 21AF04.AS Astronomy CCD Camera.

At the beginning of the article, he wrote:

A slidely modified H-alpha Telescope

A skywatcher ED100 telescope with100mm aperture/ 900mm focal lenght was modified for H-alpha observations. The original ED100 was shown to be highly corrected for the red light as published by Mr. Rohr, Germany.
