RGB align in Registax helps remove the prismatic dispersion caused by low altitude. I've taken your image, fixed the RGB and applied a bit of wavelet sharpening .... it's much better to start from the raw image rather than a JPG but this should give an idea. Lots of jet stream smearing last night. I gave up due to a combination of this and interruptions due to showers. Attachments:
