[Refurbished] Zenithstar 61 II

The ZWO ASI533MC-Pro is a high-performance cooled color astronomy camera ideal for capturing deep-sky objects, as well as high-resolution images of the Moon, Sun, and planets. Its square-format sensor, advanced cooling system, and innovative design make it a versatile tool for astrophotographers of all levels.

Key Features

• Square 1” Sony IMX533 Sensor
  Equipped with a 9-megapixel back-illuminated CMOS sensor with 3008x3008 resolution and 3.76µm pixels, the camera is perfect for framing symmetric celestial objects like star clusters and nebulae.

• Enhanced Image Quality
  The back-illuminated design improves sensitivity and reduces noise, with a high quantum efficiency (QE) of 80% and low read noise of just 1.0e. The sensor’s 50,000e full well capacity ensures bright stars remain sharp without saturation.

• Zero Amp Glow
  Features advanced circuitry to completely eliminate amp glow, even during long exposures at high gain, resulting in cleaner, more accurate images.

• Efficient TEC Cooling and Anti-Dew Heater
  A two-stage TEC cooling system reduces sensor temperature by up to 35°C below ambient, minimizing noise. The heat generated by the cooler also prevents dew formation on the camera window.

• Fast Data Transfer
  Includes a 256MB DDR3 memory buffer for stable data transfer and reduced amp glow. The USB3.0 port supports fast data rates of 20 fps at full resolution.

• Dynamic Range and Low-Noise Performance
  Offers a dynamic range of up to 14 stops, with optimal performance at a gain setting of 100. This makes it well-suited for electronically assisted astronomy (EAA) and traditional astrophotography.

Compact and User-Friendly Design

The ASI533MC-Pro is ideal for both deep-sky imaging and solar-system photography. Its compact size, powerful cooling, and versatile square sensor make it a perfect choice for astrophotographers seeking excellent performance and reliability in a streamlined package.
