S&T Test Report by Richard S. Wright, Jr.
The Poseidon-M PRO
How well does Player One Astronomy's first cooled, deep-sky camera perform?
tThe Poseidon-M PRO package comes with
everything shown here, including a 2-meter-long
(6½-foot) USB 3.0 type-C cable, a ½-meter
type-C to C cable for connecting the filter wheel
or other accessories, and a type-C to type-B
adapter cable. The package also includes two
extension tubes, an M48-to-M42 (T) adapter,

What We Like
Low read and pattern noise
No amplifier glow
Fast USB 3.0 connection
What We Don't Like
Only one port to connect
electronic accessories
THERE ARE A LOT OF NEW astronomy
cameras these days, particularly those
featuring mid-sized detectors produced
by Sony. Choosing an affordable
model from a reputable manufacturer
can be difficult. Player One
Astronomy, a relatively new entry in
the astrophotography camera market,
has been attracting the attention of
astrophotographers. The company,
based in Suzhou, China, started out
manufacturing small, USB 3.0 cameras
intended for planetary imaging
and autoguiding. We've tested a few of
these (S&T: Feb. 2022, p. 66).
Recently, the company introduced
the first model in its rapidly expanding
series of cooled cameras aimed at deepsky
astrophotographers. The Poseidon
PRO is a 26-megapixel CMOS camera
using Sony's APS-C-format IMX571
sensor. Available in both monochrome
and one-shot-color versions, we borrowed
the monochrome Poseidon-M
PRO along with a 7-position filter
wheel to see if the company's deep-sky
cameras match the quality of its other
products.

First Impressions
The Sony IMX571 sensor at the heart of
the Poseidon-M PRO is a 26-megapixel,
APS-C-format detector containing an
array of 6,252 × 4,176, 3.76-micronsquare
pixels that touts a quantum
efficiency of 91%. It can operate in 8-bit
mode (helpful for planetary imaging)
and 16-bit mode, which is best for deepsky
photography. The camera and filter
wheel arrived well-packed in a stylish
box. The build quality of the camera is
excellent. It has a red and black matte
anodized finish and stainless-steel
screws that won't rust with continual
exposure to moisture.
The round plate on the front of the
camera has M48 threads to connect to
its accessories and includes four sets
The Phoenix Wheel 7 × 36mm Electronic
Filter Wheel is 20 mm thick and accepts
36-mm unmounted filters. The company
also offers models that accept mounted
filters as well as larger and smaller formats.
