here's an interesting experiment done with image data from Oct 4.
I had very good seeing that night but I've only now had the chance to come back to it and process it the way I wanted to try out.
In addition to normal RGB I recorded several runs using a narrow B filter (400-450nm) which shows the faint clouds more clearly,
and I've added that as an overlay onto the RGB data to make this cloud-enhanced image.
Unfortunately the clouds now show all as white rather than some of the limb cloud in its natural blue colour,
but otherwise this image shows more clearly the faint clouds that were around at the time,
in particular the cloud near the centre of the image over Arsia Mons.
