Description
These two images were taken 4hours apart. The camera was tilted 41deg off N/S alignment so that the relative 1.9arcmin motion of the comet is horizontal to the viewer. Very little processing was used, save for increase saturation to highlight the subtle color shift of the inner comet. Whether a mysterious color diffraction/separation similar to that seen sometimes with the rings of Saturn or possibly a “cometbow” an interesting fact to consider is that the comet is very close to being opposite the sun. More than likely I’m just nuts but it makes a cool 3D picture
