After looking at Mars several times during the past month, I didn’t see enough detail to bother with a sketch.
I decided on this late afternoon of fine weather I would locate Mars before sunset and have a close look.
I was surprised at the detail that was visible. At 95x I didn’t see much but when I went up to high power with a 6mm ortho eyepiece (375x) and a 4mm ortho (562x) details were there. This called for a sketch.
I was using my 18” f/5 scope and the atmosphere before sunset through most of twilight was excellent for steadiness.
Clearly visible at the eyepiece were the tiny remains of the north polar cap, Mare Acidalium, Niliacus Lacus on the CM, Chryse did not appear bright, Aurorae Sinus, Mare Erythraeum and Sinus Sabaeus which seemed to blend into M. Erythraeum.
Uwe, Carlos, Kris, Ivano, dweller and others this sketch is especially for those of you still sketching Mars at this late date. I assumed I was finished in April.
