The seeing wasn't quite as good as my last sketch several weeks ago, but the increased altitude made up for some of that.

Interestingly the two sketches are of CMs almost exactly 180° apart, so they make a nice pair. Sadly, the increased altitude of the recent one meant a different angle for the binoviewer to remain seated, so the two sketches have different orientations.

Mars; 1/29/2010 23:00 UT, CM 24°; Pickering 7
400mm Mak-Cass @ 335X
HB pencil on white 160gsm paper; inverted and colourized in Photoshop

Very nice Jeff, I was out too, my seeing was III most of the time.

You picked up some great detail.

Beautiful sketch. With a lot of black around the planet it looks more real.

Beautiful sketch work! :bow: :bow: :bow:

I wish i could see the detail you are seeing. Am I missing the scope you used? A large Newtonian?

Instead I did the moon with Mars under a Portland city scape, unfinished and photographed poorly, I sent it to Spaceweather, shocked that he published it today.

I look forward to seeing your next observations and sketch work,

Mark

Mark --

16" Mak-Cass. I can't seem to sketch standing up, so Newts are out. ;)

Nice job on spaceweather.com; I like the starkness of the moon next to the colour of Mars and the cityscape.

Cheers,
-- Jeff.

Jeff

Thanks, I'll post the finished product soon; not the same now as when I sent it to Spaceweather two days ago but many of the casual observers may not see the difference.

I did not know you had a 16" Cas. Where I live now at a mountain guest home near Mount Hood Oregon, the mountain home owners next door have a 10" Cas new in box, they have no interest to set up or look through. I surmise that it may do better than my old 10.1" Coulter Odyssey. I just wish I could convince them to observe a little.

Your sketch has inspired me to seek out a larger instrument soon while Mars is close.

Thanks again for posting your excellent sketch.

Mark

Jeff,

An outstanding observation of Mars. You have captured a good amount of detail over the Martian disk. I have labeled the major albedo features noted. Thank you for sharing it with us all.

Thanks, Tommy and Carlos! (And thanks especially for the labelling; it's very helpful for us Mars newcomers.)

Cheers,

Thanks, Kris! I always wonder if what I'm sketching is going to match up with the standard albedo maps, but this one seems to more or less.

Here's a composite of the two sketches (both rotated and flipped to what I believe is "standard" presentation orientation):
