Today's Solar Prominences 29/01/13
Lots of prominence activity on the sun today.

Image details for full disc: Coronado 90mm Etalon + BF30 filter fitted to a William Optics 102mm ED f/7 doublet lens + AP 0.6x focal reducer = total focal length about 480mm. The image was captured with a DMK51 video camera, processed in Registax and then in CS5.

Image details for closeups: Coronado 90mm Etalon + BF30 filter fitted to a William Optics 102mm ED f/7 doublet lens + Tele Vue 3x Barlow = total focal length about 2145mm. The image was captured with a DMK21 video camera, processed in Registax and then in CS5.
