ALCCD12 Color Astro CCD Camera with Sony Super HAD ChipChip size 24 x 16.4 mm - Pixel 5.12 µm square - 14 MPixel - very high resolution for sharp telescopes and tele objectives
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 size, field corrector systems and other accessories can be kept.
The ALCCD12 has very small pixel - only 5.12µm. This camera is perfect for fast tele objectives, Newtonians with ASA corrector or very sharp APO refractors - all these are instruments with a high photographic resolution.
The main difference between the ALCCD 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 captured with much less integration time.
Nearly all standard DSLR cameras 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.
Choice of two different sensor filtersYou can choose between a multi-coated clear glass filter (for pure mirror systems) or an astro-optimized IR cut filter (for telescope systems containing lenses). The price is the same and the filter can also be changed by the user at a later time.
Cooling, shutter and suppression of icing:Caused by the strong TEC and specialized electronics, temperature control and dark frames are normally not necessary (thermal noise is very low). The design of the ALCCD prevents sensor icing by a dew trap. The progressive scan sensor system makes a mechanical shutter unnecessary.
