ZWO ASI585MM Mono – 1/1.2” CMOS Monochrome Astronomy Camera

The ZWO ASI585MM Mono is a monochrome astronomy camera based on the back-illuminated Sony IMX585 sensor, designed for ultra-high-resolution planetary imaging, Moon, Sun (with filter), and fast deep-sky imaging. Thanks to the total absence of amp-glow, extremely low read noise, and high sensitivity, it delivers clean and detailed images even in longer exposures.

Key Features

• 1/1.2” monochrome Sony IMX585 sensor.
• Zero amp-glow → simple and clean dark frames.
• 2.9 µm pixels for high resolution and fine sampling.
• Very low read noise, ideal for fast deep-sky imaging.
• High QE, perfect for H-alpha, OIII, and SII filters.
• USB 3.0 for high-speed planetary acquisition.
• 256 MB DDR3 buffer for stable data streams.
• Compatible with ASIAIR, NINA, SharpCap, FireCapture.
• Robust aluminum body with efficient thermal dissipation.

Excellent performance for planetary and fast deep-sky

The ASI585MM excels in:

• High-resolution planetary imaging
• Moon and Sun (with certified filters)
• Fast deep-sky imaging with bright refractors
• Monochrome EAA
• Narrowband imaging (Hα, OIII, SII)

The modern, artifact-free sensor ensures clean results and simplified post-processing.
