Today you can see a very large delicate prominence on the western limb of the Sun; it’s from a huge filament that’s been on the solar surface for the last couple of day and its now reached the edge of the limb.
It’s interesting to see these solar events as it shows what’s really happening when those dark filaments rotate to the edge the sun, plasma is continually being ejected from our Star, either passively or explosively as shown here!
When I take solar images with the Canon DSLR camera on the Monochrome setting, I’m able to capture much more delicate detail in the prominences, another thing with this setting I only have to take one image to show both the disc and prominences. Usual I have to do two sets of images at different exposures and then combined them, with this method I can get more detail on the solar surface but lose detail on the prominences. (So I’m doing it both ways now)
I’ve also coloured the monochrome image (below) using the colourize feature in the Hue/Saturation menu in Photoshop and I think it come out quite lovely :-)

Images were taken with a Lunt solar telescope and a Canon 700D camera with a 2x Barlow lens attached. To sets of images were captured one for the disc and one set for the prominences, stacked in RegiStax6 and combined in PS.
The monochrome image is one set of 20 images stacked in RegiStax6 and processed in PS, exposure time was 1/40th second and ISO800.
