Large prominence in K line and Ha 220914

About this image

Close ups of large prominence taken in Ha and calcium K line. Due to sweet spot produced by PST etalon and my having to use ROI to keep within it the prominence didn't fit in its entirety so a two pane mosaic (one for the prom and the other for the limb) had to be created,after stitching the two sets of images I used layers in PS CS2 to combine the two images. The calcium image is again two images combined using layers in CS2 and on both iamges the limbs have been false coloured.
