Another stacked Sony a7r image from a while ago tracked with the Polarie.

7 x 30 seconds ISO6400 F4 Zeiss FE55 F1.8 lens.

Processing in Adobe LR CC, PixInsight and Photoshop CC.

There seems to be some red airglow as well as a bit of green airglow in the image so that band at the lower 1/3rd is not an artefact.

Thanks Mike. No sharpening of any kind as well.




Not a bad idea. Next time I am down there I will take some more whilst its still up after dark.
