  Seeing: 5/10. Transparency: 3/5

The spc is white evident whose top limb looks depressive. Hellas shows barely its surface, but a mist or frost is seen inside.
M Hadriacum looks erased, and M Tyrrhenum slender. The npr is misty.

Use is made of a homemade 20 cm Dall-Kirkahm at f/28 equipped with a Philips ToUcam Pro.
A 1° wedge prism was employed to compensate the dispersion. Also an IR blocker is used.
Each image was made by stacking 500 frames each taken with a 1/25 sec exposure.

Location: Sakai City, Osaka, Japan
