The seeing condition is poor (2/10), and the apparent diameter is still 4.4".

Solis L seems to show up near the evening terminator. The evening mist is visible.

MORITA uses an f/7.7 Newtonian extended to f /50 having a 25 cm speculum equipped with an ST-5C (at -5゚C).

Image data are
    20 IR images each exposed with 0.1 secs
    20 R + IR Rejection images each with 0.2 secs
    10 G + IR Rejection images each with 0.5 secs
