Solar observation

After moths of not observing directly and only using remote telescopes I got some of my equipment out to do at least some solar imaging. Here are some pretty nice results

Ha mosaic of the sun - Mind the rather impressive filament

AR 11765 (seen just north of the equator in the picutre above in white light at 4,5 m focal length) 

Combination of the white light image (used for blue and green channel) and the Ha image (red)
