S23 Ultra & Gosky 12x55mm Monocular
June 25, 2024
This page provides a few examples of using the Gosky 12x55mm monocular for astrophotography with the S23 Ultra smartphone.
This very compact monocular is suitable, as demonstrated here for viewing and photographing the moon, nebulae, star clusters, some closer galaxies and double stars with wider separation.
Photos were taken with the monocular on a SmallRig CT-10 tripod. The star photographs are quite good
for this relatively inexpensive monocular. The 55 mm objective captures significantly more light than the typical ~ 4 mm smartphone camera lenses and more detail resolution (in moon shots and wider double stars) with the larger diameter lens than the typical 4-5 mm smartphone camera lens.
The Gosky 12x magnification when coupled to the S23 ultra camera using the main x1 S23 camera provides a FOV ~ 4 ° and about 1.4 ° using the x3 S23 camera. Stars down
to magnitude ~ 12 are visible in some of the 4 ° photos here which is a good FOV for capturing some brighter deep sky objects.
Photos were taken from a rural region of ~ Bortle 4.5 darkness. The 3 larger scale photos below (taken with the S23 alone or with the x1.7 Freewell lens) show 4 ° circles indicating the region photographed with the Gosky 12x55 monocular here.
