The ZWO ASI585MC Color is a powerful color camera for astrophotographers seeking maximum performance without cooling. With the modern Sony IMX585 CMOS sensor, this camera offers razor-sharp images of planets, the moon and even deep-sky objects such as nebulae and galaxies.
What makes this camera unique is its combination of high resolution, speed and sensitivity - without disturbing amplifier glow (amp glow). Its small pixels of 2.9 µm allow you to achieve stunning resolution even with telescopes as small as f/10. Perfect for detail-rich shots, without the need for a Barlow.
Key features
- Sony IMX585 sensor (8.3 MP) - high resolution of 3840 x 2160 pixels
- Pixel size of 2.9 µm - Ideal match for f/10 telescopes such as Maksutovs
- Full amp glow-free - clean images, even at longer exposures
- Frame rate up to 47 fps - sharpness by stacking or real-time observation
- PCS heat sink - Reduces sensor heat to 15 °C without active cooling
Applications
✓ Detailed planetary photography with high frame rate
✓ Capture lunar disk and solar disk in full resolution (with solar filter)
✓ Photographing deep-sky objects without cooling
✓ Taking IR shots to minimize seeing
✓ Autoguiding thanks to ST-4 port
✓ EAA (electronically assisted astronomy) with live stacking
The ASI585MC is ideally suited for users who want to achieve the maximum with minimal equipment. No cooling, no filters, no fuss - but top results. A smart investment for serious beginners and advanced users.
