A solar limb detachment is very rarely captured by amateurs in calcium light. I recorded 2 second durations, with zero second delays. This is 176 frames total. A celestron luminos 2.5x barlow was used with a skybender optical tilt mechanism and a 0.5 angstrom calcium k3 core filter system that i designed. What you see appear’s similar to hydrogen alpha, but this is indeed calcium light centered at 393.37nm A false color version can be seen on my flickr page linked below. https://live.staticflickr.com/65535/51295734103_7af7e99175_o.gif
