Seeing detail is now very difficult. Especially with the seeing at 1/5-2/5.
Telescope 18” f/4.8 masked to unobstructed 8”, creating f/10.7, 6mm eyepieces 366x, filters used neodymium and single polarizing to improve contrasts. Syrtis Major, Iapygia, Mare Serpentis, Sinus Sabaeus, Mare Tyrrhenum in part, Utopia all visible along with Hellas. Limb brightening from south through preceding limb to the north.
