Equipment Details:

Smartphone camera on Motorola G-Pure looking through a 76-millimeter terrestrial telescope at 22x. Mobile phone camera held afocally before the eyepiece.

Post-processing Details:

GNU Image Manipulation Program (GIMP) on GNU/Linux. (1) rotation by +21 degrees; (2) crop from the original at 4,160 x 3,100 to 2,400 x 2,400; (3) scaling to 1,200 x 1,200.

Image Details:

A very young moon, perhaps my thinnest image (and sighting) ever at 1 day and 2 hours. This was taken when the moon was only 8 degrees above my western horizon, which is badly obstructed by trees and power lines. The sun was then 5 and a half degrees below the horizon, which explains the reddish color typical of a deep civil twilight. My latitude of 18 degrees north does help a bit with young moons like this one, because the ecliptic falls year-round at a steep angle against the horizon.
