S23 Ultra & SVBONY ED 20-60x80mm Monocular
Dec 2024
This page provides a few initial examples of using the SVBONY ED 20-60x80mm monocular for astrophotography with the S23 Ultra smartphone. Exposures and focus are manual in Pro mode using the main X1 W camera. No star tracking was used so some slight star-trailing is evident. Except for a small amount of sharpening in some images, no other image filters or modifications were used.
This premium ED monocular is suitable for viewing and photographing the moon, nebulae, star clusters, closer planets and galaxies and double stars with separation wider than ~ 4 ∠ ".
The 1.6 kg monocular was mounted on a K&F tripod with suitable 10 kg capacity.
A CelticBird phone adapter was used to couple the S23 Ultra smartphone to the monocular eyepiece.
The 80 mm diameter 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 mm smartphone camera lens.
SVBONY claims an angular resolution of 2 ∠ " for this monocular (the theoretical Dawe's limit resolution for a perfect 80 mm objective lens is ~ 1.5 ∠ ").
Carefully measured visual field of views for the 20-60x zoom range are:
20X 1.91°
40X 1.23°
60X 0.95°
