Description
The cameras ALccd-QHY 163, 174, 178, 224 and 290 are based on state-of-the-art CMOS sensors, with sensor diagonals of up to 22 mm. The models are essentially different in terms of sensor and pixel size and whether it is a BSI (Back Illuminated) or FSI (Front Illuminated) sensor.
The cameras are very compact, which is especially useful for smaller portable telescopes, but even in special technical components, a small camera is an advantage.
The built-in DDRII cache has a memory size of 128MB and ensures that no images are lost during download. It is also the prerequisite for even with low-performance PCs and USB 2.0, no image loss or even to be able to download an image.
The sensor chamber of cooled cameras is sealed and heated with a special heater. Thus, fogging is counteracted, especially in high humidity applications.
The sensor does not require a mechanical shutter, it works electronically. The ALccd-QHY 174 model with global shutter , the other models with roller shutter .
The series includes various light sensing techniques, via BSI (backlight) or Classic FSI (front lighting). BSI sensors, such as those used in the ALccd-QHY 178 and 290 models, usually have a higher photosensitivity due to the characteristic properties of these sensors.
For operation, the ALccd-QHY 163, 174, 178, 224 and 290 cameras require a 12 V power supply . The connection is screwable and stable plugged into the power plug.
