ASI2600 Series — APS-C, 16-bit, Deep-Sky Workhorses
The ZWO ASI2600MM Pro (Mono) and ASI2600MC Pro (Color) cameras are high-performance deep-sky imaging tools built around Sony’s back-illuminated IMX571 APS-C sensor. Both feature 3.76 µm pixels, a true 16-bit ADC, ultra-low read noise, and a large 73 ke⁻ full-well capacity for incredible dynamic range.
ASI2600MM Pro (Mono)
- Peak QE up to 91% for maximum sensitivity
- True 16-bit ADC for smooth gradients and precise color
- Full well capacity 73 ke⁻ with 1.0e⁻–3.3e⁻ read noise
- APS-C format 23.5 × 15.7 mm, 6248 × 4176 resolution (26 MP)
- Two-stage TEC cooling Δ30–35 °C below ambient
ASI2600MC Pro (Color)
- One-shot color simplicity—no filter wheel required
- True 16-bit ADC and 73 ke⁻ full well
- Low read noise (1.0e⁻–3.3e⁻)
- Peak QE ~80% for excellent broadband and dual-band use
- Two-stage TEC cooling Δ30–35 °C below ambient
Key Features
Integrated Anti-Dew Heating – The heater ring around the protective window keeps condensation away for clear optics during long exposures.
Adjustable Sensor Tilt Plate – Easily fine-tune corner stars for a flat field, ideal for fast optics.
True 16-bit ADC – Smoother gradients and higher dynamic range compared with 14-bit sensors.
Power and Connectivity
Both models feature a USB 3.0 interface with dual USB 2.0 ports for connecting accessories such as an EFW or guide camera. A 12 V power input is required for the cooling system.
Power Requirements: Use a regulated 12 V DC 3–5 A adapter (5.5×2.1 mm, center-positive) or lithium battery (11–14 V). Over-voltage activates built-in protection.
