Astro Camera GPM585M

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

Specifies the total number of pixels. With this handy value you can compare the resolutions of different cameras.

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.

For long exposure times, many CCD cameras are cooled to reduce thermal noise and achieve higher image quality. CCD cameras are grouped into three categories:
- no cooling
- passive cooling via cooling fins
- active cooling (e.g. using a fan and Peltier element)

Specifies the product's connection or connection thread on the telescope connection end. The same adapter dimension must always be available on the telescope.

This camera takes not just one picture, but a certain number per second. Often this value is given the abbreviation "fps" or frames per second. With a high number of images, you can use the advantage of "freezing" the image and the seeing and thus later creating the perfect image.

The full well capacity indicates how many electrons a single pixel can hold. The larger the chip, the more sensitive it is to light, and the more electrons it can absorb. But what does that mean? The noise is reduced at a large full well capacity and the ability to reproduce very bright and dark objects simultaneously increases.
