Carlos,

I have admired your Mars sketches for many years. Fantastic work. I am really glad you post your Mars sketches here at CN.

Great sketches.

On Christmas Eve I saw similar features that Carlos had rendered with my nephews. I did not have time to sketch as my nephews were more interested in trying to find Santa.

Best wishes to everyone for a happy, healthy and prosperous New Year!

Carlos and Jim,

Interesting to see two such different approaches to sketching Mars both made from very careful and detailed observations--well done!

Frank, Sol, Michael,

Thanks!

it actually did take the entire 3 hrs. to see/sketch that fine detail...by far, the most fine detail i`ve seen/sketched on this side of mars so far this apparition...it`s also the longest session out in the cold this apparition...

Thank you all for the wonderful compliments on my latest observation of Mars and observing skills. I was very happy to be observing Mars again. The best of luck in your own observations of Mars.

Happy New Year!

I made a pair of observations on December 28, 2007 using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain. I noted a significant amount of detail over the Mare Cimmerium and Elysium regions of Mars. I welcome any comments on my observations.

Date (U.T.): December 28, 2007
Time (U.T.): 01:20 (left image, IL) and 01:50 (right image, Wratten 38A)
CM: 227.5*W (left image) and 234.9*W (right image)
Ls: 009.0* (Early Northern Spring/Southern Autumn)
De: 0.7* North, p 1.00, Dia. 15.7"
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 163x, 273x, and 359x
Seeing (1-10): 6-7, Antoniadi (I-V): II
Transparency (1-6): 5

Notes:
01:20 U.T. (Left image, CM 227.5*W, IL): The South Polar Region (SPR) appears obscured by a very bright to extremely bright (8-9/10). Mare Australe appears dusky to shaded (4-6/10) north of the haze. Electris, Eridania, and Ausonia appear to be obscured by a bright to very bright (7-8/10) haze. Mare Cimmerium appears dark to dusky (3-4/10) and mottled. The northern border of Mare Cimmerium contains projections (Laestrygonum Sinus, Cyclopum Sinus, and Cerberi Sinus, preceding to following). "Valhalla" was visible north of Mare Cimmerium as a dusky (4/10) band. Hesperia appears as a bright (7/10) diagonal strip between Mare Cimmerium and Mare Tyrrhenum. Mare Tyrrhenum appears dark to shaded (partially obscured by a very bright (8/10) morning limb haze (MLH). Zephyria, Aeolis, Aethiopis, and Aetheria appears bright (7/10). Amazonis and Arcadia appear dusky to shaded (4-6/10) and mottled. A very bright (8/10) orographic cloud is visible over Olympus Mons over the north-preceding (evening) limb. Trivium Charontis, Phlegra, and Azania appear dark to dull (3-5/10). The Propontis Complex (Propontis I and II, Castorius Lacus, and Euxinus Lacus) appears dark to dusky (3-4/10). Elysium appears bright with a very bright (8/10) cloud over it's north-preceding sector. Panchaia appears bright (7/10) and Lemuria (dusky (4/10). The Hyblaeus Extension appears dark to dull (3-5/10) following Elysium. Syrtis Major appears to be obscured the very bright (8/10) MLH. The North Polar Cap (NPC) appears brilliant (10/10) along the northern limb.

01:50 U.T. (Right image, CM 234.9*W, Wratten 38A (Blue) filter): Mare Cimmerium appears dusky (4/10). The southern limb, preceding (evening) limb, northern limb, and following (morning) limb appear very bright (8/10). A very bright (8/10) orographic cloud appear over Olympus Mons over the preceding limb. A very bright (8/10) cloud appears over Elysium.

The best of luck in your own observations of Mars. A digital image produced in Corel Painter X.

Regards,
Carlos

Carlos,

A pair of beyond beautiful sketches. I sat with a map as I read the tour guide you added. Great post.

great sketch, you seem to be seeing a lot of stuff in the northern hemisphere which was a bit blank in the 03 opposition,perhaps this is due to the different tilt Mars is giving us,i really like your computer sketches they are very realistic as to the texture of mars as seen in the eyepiece.

Carlos,

at it again i see

a couple more outstanding sketches...somehow, your sketches are good enough that they make the, 'quiet side', of Mars look not so quiet...lots of detail in your sketches...and that blur for realism is the icing on the cake...superb, detailed report, too...looking forward to more...

I truly appreciate all of the wonderful compliments on my latest observations of Mars. I was impressed by the amount of detail visible over this longitude of the red planet. I am always trying to improve my rendering techniques. The best of luck in your own observations of Mars.

Mars 12.30.07 new [Re: CarlosEH]
      #2082729 - 12/30/07 05:11 AM Attachment (73 downloads)

Hi.

I had great seeing conditions tonight for Mars observing. Probably my best view yet for this apparition.

I used a bunch of pencils and a very light touch. I think I used 4H, 2H and 2B pencils. Blending was done with fingers. My eraser shield really got a workout on this one.

Other details are written in the sketch.

Best,

great to see a sketch from you again, Sol...another outstanding sketch with lots of fine detail...

hope you give the 3" refractor another work-out to see what you/it can do on Mars just after opp...

looking forward to your next sketches...regardless of scope used...
