Solar Northern Hemisphere In Calcium Light - 26th March

 The suns northern hemisphere was by far the most interesting and most active today, with a new active region forming quite rapidly over the past 24 hours or so.  Numerous spots were visible in it, and several bright points could be seen crackling away.  The smaller scale image was taken with the 40mm scope and 2x barlow to push the focal length to around 800mm.  This along with the PGR Chameleon 3 gave a pleasing image scale.  The lower image was taken at 80mm aperture and 2000mm focal length, but all the haze, high cloud and contrails were not helping the seeing conditions or the transparency.  Regardless, it was nice to get some imaging in after a start to the year beset with poor weather conditions.
