About this product

New TRIUS Cooled USB3 CMOS Cameras from Starlight Xpress.

CMOS technology is moving ahead at a fast rate. With Quantum Efficiencies (QEs) starting to rival those of traditional CCDs, along with low read-noise figures, some slightly below that of our CCD cameras, CMOS is starting to become a viable alternative.

For fast planetary imaging, CMOS is now the dominant sensor, however, it does suffer from amplifier glow which is inherent in all CMOS sensors and is a problem for deep-sky imaging. Many users stack large numbers of short images together to achieve a longer exposure time, and this method is useful to help reduce tracking and seeing errors. But it has always been virtually impossible to eliminate amplifier glow without post-processing techniques, which means manipulating the raw data, often before it arrives at the computer. The engineers at Starlight Xpress were not about to be beaten! After working for a few months, experimenting with various clocking routines we have developed a methodology that will allow you to take up to 15 minute exposures with minimal glow, while maintaining your raw data. We call this our "No Glow Technology". (Even Sony have asked us how we do it!)

As with all the TRIUS range of cameras, a USB hub is incorporated into the main camera offering 3 x USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200mA, and is able to drive a Lodestar, or UltraStar for guiding and another two USB ports for our USB filter wheels etc. This integration greatly reduces the number of cable trails back to the computer and gives less potential cable tangling around the mount during your imaging session.

New 3 stage Peltier cooler combinations have been designed into the CMOS TRIUS cameras, along with the Argon-filled sensor chamber for delivering good cooling to the CMOS sensors.
