another mars sketch 16 april

seeing wasn't great for this sketch of mars, but i managed to see some detail over the disk. the polar cap is really small now, and the planet looks hazy with brighter regions at the preceding and following edge as well as the south polar region. this may offcourse be just me not seeing very well on a small disk because i wasn't able to resolve sinus sabaeus from mare erythraeum!

That is a beautiful late season sketch of Mars. I know for sure you will keep going on these wonderful renderings. As for myself it is getting tougher faster.
I was showing Mars to my non-observer wife last evening and she thought it had a nice color but looked kind of minuscule.

Another nice sketch from Mars. I hope you don't have to redraw your map now
What was the smalest Mars you ever observed with (some) detail on it?

An excellent observation of Mars, especially at such a small apparent diameter (8"). You were able to record a good amount of albedo features in less than perfect seeing. You probably did not detect Sinus Sabaeus because it appears there existed a bright haze over the preceding (evening) limb. I labeled the most prominent albedo features. Thank you for this and all of your other wonderful Mars observations made during the apparition.

Jef: 30th June last year was my first sketch this apparition, mars was only 4,9" but syrtis major and hellas were on view, it helps when a large, dark and distinct feature is in view then.
i don't think i'll be able to spot some detail on the jovian moons though like Leo Aerts and others here like Carlos!
