Mars – December 28, 2009

Mars
Mars – CM 313°
Sketch and Details by Kris Smet

Finally some good seeing tonight, i had a beautiful view of syrtis major, hellas, sinus sabaeus and the north polar region. finally some subtle darkness differences in syrtis major could be made out; where mare tyrrhenum runs into syrtis major and the northern tip was dark and kinda triangular. the little ‘bended hook’ was also visible. sinus sabaeus was also a bit darker. after a while i thought to see some irregularity in the npc/nph border, like a bit of it sticking out, slightly isolated.
Lybia & Aeria showed as bright patches, i guess Lybia could be clouded because it showed up brighter in blue light than Aeria.
the deucalionis region (in between sinus sabaeus and noachis) also looked brighter, but i think that might just be due to the it’s position between two darker areas.

Hopefully we can get a few more nights like this in january! it’s good sessions like these which make you forget previous frustrating views

I used my 8″ dob for this one @ 357x without filters.
the sketch is simply scanned and a bit unsharpened, no further color, brightness or contrast enhancements.

location: bornem, belgium

  1. Kris,
    You are lucky guy, You were able to use such HUGE power in European condition! 😀
    The sketch is very good. I see, You painted lots of surface details and the planet “bright border”.
    Has anyone idea what is the nature of “bright border”? Is it illusion or something else?
