DFK 21AU618, USB colour camera

Specifies the type of camera, for example: CCD camera, SLR, webcam or planetary camera.

The high sensitivity makes it particularly suitable for deep sky imaging.

The chip size comprises the outer dimensions of the chip. The larger the chip, the larger the image field produced.

Specifies the edge length of the mostly square pixels that make up a camera sensor.

The image format describes with which type of file the captured image can be saved.

Each CCD camera tends to produce image noise, an interference that appears as a kind of unattractive grain on the image. The issue is especially important with longer exposure times. In addition to the general noise, there is also a noise generated by the process of reading the image: the read noise.

Microlenses increase the light extraction efficiency of a sensor.

The bit depth is also referred to as the dynamic range of a chip. The number of bits in a picture also determines how many different shades of grey can be displayed. The depth of the image information depends directly on it. In an image taken with 1 bit depth, you will only see black and white dots. In this case, you can hardly call it a picture. Many details that the naked eye can discern are missing. 16 bits means the presentation of more than 65.000 shades of grey.

The maximum exposure time in minutes that is possible with this camera.

A camera that takes over the automatic tracking control during exposure, and corrects it independently.

A filter thread is a fine thread into which 1.25" or 2" astronomical filters can be screwed.

This refers to whether a filter wheel is integrated in the camera housing, or is included in the scope of delivery as an external filter wheel.
