The new ZWO ASI 664MC colour camera can be seen as an improved version of the ASI 662MC – at least in terms of resolution, sensor size (= larger field of view/FOV) and readout noise.
The ASI 664MC also offers a very high resolution and is therefore perfect for moon and planet photography. But EAA (Electronically Assisted Astronomy) and DeepSky astrophotography are also possible with this uncooled camera. This CMOS camera is equipped with a modern 1/1.8" sensor with 2704*1536 pixels. In addition to modern back-illumination technology, the Sony IMX664 sensor offers an extremely smooth image without amplifier glow (amp glow) and also impresses with its excellent resolution (2.9µm pixels) and a high frame rate of 95fps. The ZWO ASI 664MC is therefore particularly suitable for detailed planetary photography and high-resolution images of the moon's surface, solar photography (always use a suitable filter!), images of compact, brighter nebulae (planetary nebulae) and globular clusters. Exposure times of up to 2000 seconds are possible.
This camera model can also be used very well for infrared photography (less seeing influence) or as an autoguider.
The extremely high resolution, combined with a high frame rate of 95 fps (RAW8 format), also enables real-time observations of planets and details on the Sun and Moon. The built-in clear glass filter prevents dust from entering the sensor. With the right selection of contrast filters, nebulae filters, IR pass filters or UV/IR blocking filters, you have full control over which light falls on the sensor.
