More Moon, June 2020

June 1st, 2020, 10:00 p.m. local time

Continuing my recent series of evening backyard excursions targeting the Moon, I brought the big telescope out again for a look at the larger Gibbous phase, now just a few days away from Full.  The sky was clear and bright, illuminated from the Moon’s reflection.  It made observing anything around the Moon difficult, especially in my light polluted skies.

The only post-processing note is that I tried to get the overall sharpness, contrast, and brightness as close to the image from two nights ago as possible.  I like that prior image better.  Frankly, the Moon gets less interesting as it approaches Full, as the shadows creep behind the Moon and away from the Sun, revealing less crater shadows.
