QHY8L Color CCD Camera - 28.5 mm sensor 

ALccd cameras are designed for the requirements of ambitious and advanced amateur astro photographers.

It is recommended for those who want to step up from a standard DSLR camera to a "real" astro CCD camera without the need of changing the whole accessory system. Because of the similar sensor sized, field corrector systems and other accessories can be kept.

The main difference between the ALccd8L and DSLR cameras is: The Astrolumina camera does not share their disadvantages. DSLR cameras have an IR cut filter in order to deliver sharp and colour-balanced images. For astro photography, blocking near IR is normally not wanted and the result is that H-alpha emitting objects like many gas nebulae can be captures with much less integration time.

Nearly all standard DSLR camera have a data depth of 12 bit (4096 levels of grey). For astro imaging, this is not optimal. ALccd cameras work with 16 bit - the advantage is obvious. You gather more contrasty pictures and a fainter limiting magnitude.

Cooling, shutter and suppression of icing:

The design of the ALccd prevents sensor icing by a dew trap.

The progressive scan sensor reading system makes a mechanical shutter unnecessary.
