Saturn spent 2018 in the constellation Sagittarius, unusually bright as it always is here because its rings are about as wide open as they can be and therefore offering a greater surface area to reflect light. This evening, Saturn is at magnitude +0.06, which makes it approximately the brightness of Arcturus and a tad brighter than Vega. Unannotated image
electron decay from n = 3 down to n = 2 (which glows red) well at all, but the less frequently occuring decays from n = 4, 5, or 6 down to n = 2 (resulting in blue and violet light) does show up well in the camera.
Saturn is in the neighborhood of the great globular star cluster M-22 with the smaller globular cluster M-28 also in the field. I decided to convert that image into black and white because my Canon renders everything with a strong reddish cast because its IR filter has been modified for the purpose of allowing strong red colors to be captured.
