Nice image and an interesting comparison between the visual and the infrared. I must criticize the diffraction spikes. They look artificial, and the image would be better without them.

Beautiful image except for the artificial diffraction spikes. If your imaging system does not naturally produce them, don't add them in post

Diffraction spikes? From a refractor?

Beautiful picture but digital sharpening in post-processing is evident.
