Mars March 3, 2021
Mars 2021-03-03 (UT) In March, Mars has already passed its zenith in the evening and is lined up near M45 (Subaru) in the western sky. The visual diameter of Mars has decreased to the 6-second range and the observation season is over, but the feature can still be captured depending on the airflow. Aurorae sinus and Solis lacus can be seen in the Martian feature. (Stopped 45cm Newtonian to 30cm)

Canes Venatici Galaxy-2
Canes Venatici Galaxy-2 2021-02-22 There was a faint diffused nebula pattern spreading like a fan to the south of NGC5353 in this galaxy image. It doesn’t seem to be a ghost because it was also in other images. It may be a big one, including the neighboring NGC5354. If you have any information, please give me a professor.

M57 (Lyra, Ring Nebula. Luminous intensity 9.0 mag, apparent diameter 2.5′).
M57 (Lyra, Ring Nebula. Luminous intensity 9.0 mag, apparent diameter 2.5′). A white dwarf (15th magnitude) in the center of the nebula. Next time, I would like to see it with a 45cm reflection. C1296 (14th magnitude star) on the upper right is a dark and pale galaxy.
