BC = 1. SPC has dull rift ~320 areographic longitude. Hellas surface features, i.e., Zea Lacus and part of Peneus visible through haze. Evening limb cloud over Hardriacum. EH, NP Hood bright, MH and morning cloud over Argyre. Sky clear and steady, when up to over 1000×. With my eye problems this magnification is becoming difficult to use. In perfect seeing I can stretch the 16" f/6.9 to the highest limits with no apparent deterioration in contrast or image quality. New Spectrum Coatings aluminum coat makes a difference.
