Alta U9000HC Specifications
The Alta U9000HC uses a very large format 9-megapixel full frame sensor with anti-blooming gates, ideal for applications requiring large field of view, such as astrophotography, sky surveys, and radiology. The HC version increases cooling by 20C compared to the U9000 and is available with liquid circulation only. For complete CCD specifications, including cosmetic grading, see data sheet from manufacturer.
In the June 2007 issue of Sky & Telescope in an S&T Test Report, Senior Editor Dennis di Cicco had this to say about the Alta U9000: "The quality exceeds anything I've been able to do in the past with fi lm or any other CCD camera."
