Uranus-C Pro USB3.0 color Camera (IMX585)

Product Overview

The Player One Astronomy Uranus-C Pro is a cooled one-shot-color USB3.0 camera built on the 8.3-megapixel Sony IMX585 CMOS sensor. The IMX585 is a 1/1.2″ sensor (12.85 mm diagonal, 3856 × 2180 pixels, 11.2 mm × 6.3 mm imaging area) with 2.9 µm pixels, a 47 ke- full-well capacity, and a peak quantum efficiency of about 91% that extends well into the near-infrared. It reads out at up to 47 fps and cools 35°C–40°C below ambient, so it crosses over between high-frame-rate planetary work and cooled deep-sky imaging.

Who It's For

This is a good match if you want one camera that handles both planetary lucky imaging and cooled deep-sky exposures. The small 2.9 µm pixels and high frame rate suit the Moon and planets at long focal length, while the cooling and strong near-IR response make it capable on nebulae, comets, and IR-pass targets.

Key Features & Design

• Sony IMX585 color sensor: 3856 × 2180 with 2.9 µm pixels and standout near-IR sensitivity.
• Peak QE about 91%: very efficient for a color sensor, including deep red and near-IR.
• Read noise down to 0.7e-: an exceptionally low floor for short and long exposures alike.
• Up to 47 fps, 12-bit ADC: high frame rates for planetary lucky imaging.
• Two-stage TEC, 35°C–40°C below ambient: very low dark current (0.0004 e/s/pixel at -20°C).
• 512 MB DDR3 buffer: steadies the USB3.0 data stream during fast capture.

Optical / Mechanical Design

The IMX585 combines fine 2.9 µm pixels with a very low read noise floor (0.7e-) and near-IR-extended QE peaking around 91%, which is what lets a single sensor serve both planetary and deep-sky roles. Cooling drives dark current to just 0.0004 e/s/pixel at -20°C, and a D32 × 2 mm AR Plus multi-layer coated window protects the sensor.

Recommended Uses

• Planetary and lunar: high-frame-rate lucky imaging at long focal length.
• Cooled deep-sky: nebulae and comets with low thermal noise on long exposures.
• Near-IR imaging: IR-pass planetary and specialty work using the sensor's extended red response.

Compatibility & Accessory Notes

The Uranus-C Pro connects over USB3.0/USB2.0 and powers its cooler from a 12 V DC input. It uses a 1.25″ fit and M42 × 0.75 threads, with the sensor set 17.5 mm behind the front face. Use that 17.5 mm back focus as your reference when adding a Barlow for planetary scale or a filter and flattener for deep-sky work.

Good to Know Before You Order

• Small sensor, small pixels: the 1/1.2″ frame excels at planetary scale; for wide deep-sky fields a larger-sensor camera covers more sky.
• It is a dedicated imaging camera: it works through a computer and has no application in a visual eyepiece train.
• Cooling draws 12 V power: plan a 12 V DC supply alongside the USB cable.
• Spacing help: the 17.5 mm back focus is your reference — send us your Barlow or filter setup and we will confirm the spacing.

Frequently Asked Questions

Is it difficult to set up?

No. It threads onto a 1.25″ or M42 interface, connects with a single USB3.0 cable, and takes 12 V DC for cooling. Capture software controls frame rate, gain, and cooler set-point.

What is it best used for?

A versatile planetary and cooled deep-sky camera — high-frame-rate lunar and planetary capture, plus low-noise nebula and comet imaging.

Is it good in near-infrared?

Yes. The IMX585 keeps high QE well into the near-IR, which helps IR-pass planetary imaging and cutting through poor seeing.

Can it do deep-sky as well as planetary?

Yes — the cooling and 0.7e- read noise make it capable on long exposures, within the field its 1/1.2″ sensor covers.

Bottom Line

In short: a cooled one-shot-color camera on the near-IR-sensitive 8.3 MP Sony IMX585, with 2.9 µm pixels, 0.7e- read noise, up to 47 fps, and 35°C–40°C of cooling below ambient. Give it 12 V power and a USB3.0 link and it moves easily between planetary lucky imaging and cooled deep-sky work, set 17.5 mm behind its front face.
