H-alpha images Coronado PST/Coolpix 4500

Yesterday morning the seeing seemed to be good. The Sun
revealed a great number of details in the PST. There where
filaments, prominences, plage's, and active regions visible.
I shot some images with the Nikon Coolpix 4500, which I
included in my observing report. Before publishing the images,
I fiddled around with adjusting the images in different colour
channels (see Sky and Telescope July 2004). It produced some
interesting results that form a base for future improvements.
