Mars 21st July good seeing

[John Hothersall]

SPX350 F41.3, PGRFlea3, Baader RGB filters.

Got another chance at Mars boring side with better cloud detail round North Pole. Imaging earlier an earlier looks like my last planets for a while.

Regards, John.

Good work John, I did take a peek at Mars the other night, but it was too small to attempt with my imaging set up. Impressive image scale and detail.

Cheers

Another fine image John. Those streaky clouds are quite distinctive. I'm going to keep having a crack at Mars for a little longer, but it is getting harder to get a lot of detail, especially with a lot of dubious seeing around!

Well, I guess when they finally break the Hubble, they can come to you. I still don't quite know how you do it, but I'm in awe.

I'm curious - are the clouds that are on the limb in the middle latitudes (ie, at neither the north or south pole) apparent simply because of the oblique angle we are looking through them? Or is it more to do with the terminator causing some local weather event due to the 120 degree temperature difference between day and night?

Cheers

Excellent John, lovely cloud details in the blue channel.

Thanks everyone.

Yes Markus only North and South offer a permanent curve gathering up cloud and ice. There is cloud everywhere but when the planet rotates the edge gets to the centre where the thin atmosphere blends the thin cloud away showing the surface. The Volcanoes show lots of cloud when they are at the limb but a lot less cloud when they are at the centre.

Ahh, makes sense. Thanks - for the images and the information :-)
