The ALccd-QHY 10 colour camera is the model in this series with medium-sized pixels (6.05 µm).
It is comparable to a digital single-lens reflex camera (DSLR) in terms of chip size, but offers many advantages over an SLR:
- The DSLR is designed for daytime photography and has a filter built in front of the chip that blocks red light (H-alpha). However, blocking long-wave light is not desirable in astrophotography. The frequently encountered H-alpha line (gas nebula) is almost completely unregistered by DSLRs. The ALccd QHY camera has a different filter and is sensitive across the entire range from approx. 350 to 700 nm.
- Almost all standard DSLRs work with a data depth of 12 bits, i.e. 4,096 grey scales. This is not ideal for astrophotography. The ALccd QHY cameras have the full data range of 16 bits. The advantages are obvious. Under the same conditions, you achieve better differentiation between light and dark, a higher limiting magnitude and significantly better colour differentiation.
- The ALccd-QHY camera does not require an optional T-ring for attachment to the telescope, spotting scope or microscope, as a suitable T-thread is already integrated into the housing.
Further advantages:
- The camera is designed to prevent the chip or cover window from icing up (moisture trap).
- Due to the readout method (two-field readout), no mechanical shutter is necessary.
- Compared to other CCD cameras, this camera impresses with its small and lightweight housing. This puts little strain on the focuser.
The camera can lower the temperature of the sensor to around minus 40° ambient temperature using advanced cooling and a new housing. The temperature is controlled via the supplied DC201 control box and the camera's control software.
