Quote:And here is an another Belgian Mars from Newyearsday!Like Kris said the seeing wasn't that good. At x300 I had to wait all the time for moments of steady seeing. But I'm happy that I finaly saw the "good" side of Mars. And when you like for some time you see Mars rotate!
Quote:@Kris: I finally managed to see something on Mars with my ETX-70! The polarcap was by moments visible @ x87. I tried x150, but then Mars looked like it was on fire! For the Moon this small refractors works fine, but for planets the optics is to bad. Thanks a lot for encouraging me in the past (at the Urania discussion forum) for observing Mars.

Quote:Yes, Syrtis Major looks a lot different this time around. Much more pointy than last time around, and the wierd thing about the tip is that it's slightly hooked but that we're seeing the (Ikemura/Newt convention) *left* hand side as darker, with the right hand side rather less contrasted; last time around it appeared less pointy and with a darker hook following the *right* hand then bottom side.
Quote:What's striking is that you can see the spur at the left side much better thna in 2007, although I see it somewhat lower (more to the North) than you do, and with a blotch in Syrtis Mahor that's definitely less dark immediately under the lighter cut into it.
Quote:On the other hand, I did see Sinus Sabaeus, which is very striking this apparition, much more narrow, with the region North of it clearly lighter than the central plains (and no, I don't think it's a subjective contrast effect; it also appears mcuh more clearly with a Baader Moon&Skyglow and at higher powers).
Quote:A fine showing of observational skills from Belgium.
Mars must be a fantastic sight in your 40 cm telescope!
