Explore ZEUS 455M Pro
Capture expansive deep-sky fields with a 36 x 24 mm Sony IMX455 mono sensor, 9576 x 6388 resolution and finely spaced 3.76 µm pixels. Two-stage TEC cooling supports a controlled long-exposure workflow, giving enthusiasts a detailed platform for narrowband and broadband imaging when their telescope and accessories suit the full-frame format.
Sensor: IMX455 mono
Format: 36 x 24 mm (Full-Frame)
Max Resolution: 9576 x 6388 (61 MP)
Pixel Size: 3.76 µm
The camera uses the IMX455 sensor with 61 megapixels at 9576 x 6388 resolution and 3.76 µm pixels. That combination increases sampling detail across a 36 x 24 mm full-frame area, letting you resolve fine structure in nebulae and crowded star fields when paired with suitably large optics.
Two-stage TEC cooling is designed to limit thermal noise during extended exposures, with a specified Delta T of 35 °C ±2 °C below ambient. The cooler can draw up to 12 V and 3 A, so cooling adds a meaningful power requirement to an imaging session. Plan the cooler supply separately from the USB data connection.
Normal mode prioritises higher frame rates, while Low-Noise or HCG mode is intended for lower read noise and higher dynamic range in deep-sky work. The specified readout-noise range is 4.2 to 1.27 e⁻. Native 16-bit conversion provides 65,536 levels, helping preserve subtle grayscale transitions through processing.
The rear four-point sensor tilt plate lets you adjust the sensor corners to help reduce field curvature, while its high-density sponge shading pad helps block stray light from side openings. Supplied hardware includes M54 and M42 adapters and extenders, T-mount and 1.25-inch covers, three USB cables, an air blower, hex wrench, screws, cable tie and camera bag.
A Type-C USB 3.0/USB 2.0 connection supports capture at up to 6.5 FPS in RAW8 or 3.2 FPS in RAW16 at 9576 x 6388 via USB 3.0. Exposures span 32 µs to 2000 s, covering brief captures through long deep-sky integrations. Allow for the separate 12 V cooler supply when using TEC cooling.
