Good all-round beginner astrophotography camera

5/5. I have rarely purchased a piece of equipment that felt like money better spent.

I have a 4" Star Watcher SkyMax 102 (1300mm focal length) mounted to a Star Adventurer 2i, and have been doing astrophotography (AP) as a hobby with my Olympus OM-D E-M10 II for about two years now. I'm no expert, I only have so much time to devote to learning/executing the craft, and only so much money to spend on equipment.

I decided to get a dedicated AP camera that could be used as a guide camera, used for planetary imaging and, in a pinch, used for DSOs too, and all without the hassle of needing filters to do colour photography. Megapixels were of little concern to me, and some simulation in Stellarium suggested the ASI662MC was the right fit. It did not disappoint.

Photographing the Dumbbell Nebula was a breeze with the ASI662MC. Even at its highest gain for DSOs (450), live-stacking 1,025 5-second exposures yielded the lowest-noise, best deep sky images I have ever taken---and this on my second night with the camera. ZWO's software, providing separate interfaces for planetary and DSO imaging and live stacking, has clean interfaces for each and makes working in the field with it easy.

I'm still learning planetary imaging, since this camera is my first foray into it, but some initial attempts at Saturn were promising. Its fast maximum frame rate of 107.6 fps means my main concern is filling up my SSD, and the 128 MB buffer meant I never missed a frame.

主KV

The ASI662MC/MM is equipped with the Sony-IMX662 rolling shutter CMOS. Boasting a 1/2.8” frame size combined with a 2.9μm pixel size, it features 2.07 million pixels (1920×1080), and possesses both high sensitivity and low read noise characteristics. In high-speed mode, it can output 107.6 frames per second, providing reliable support for planetary observation.

4 Unmissable Advantages

性能介绍

Large full well capacity, not easy to overexposure

The ASl662 adopts Sony lMX662 sensor with the latest technology.

Compared to the previous generation of sensors, it has very low readout noise and an extreme large full well capacity. This helps effectively avoid overexposure issues and also allow longer exposures. In low light conditions, the camera performs excellent, capturing very clear images of celestial objects.

背照式

256MB DDR3 & USB 3.0

The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission.

No Amp Glow

ASI662 exhibits zero amp glow, no matter how long the exposure and how high the gain value. Since it is implemented directly at the hardware level, it does not require software control.

Note: This technology is implemented directly at the hardware level and requires no software control.

Camera Curve

Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better. As can be seen, the readout noise of ASl662 is very low compared to CCD camera. The built-in HCG mode can effectively reduce the readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.

When the gain is 252, the HCG mode is automatically turned on and the dynamic range to 11 stops.

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio.

The peak quantum efficiency of ASI662MC is 91%.
