The perfect camera for short focal length refractors
The latest addition to the TRIUS camera range, the PRO-834 uses a 12 megapixel Sony CCD with 3.1uM square pixels. This very high resolution chip is well suited to short focus optics, especially compact refractors. The new PRO board design has given this camera an exceptionally low readout noise figure of better than 3 electrons RMS and a fast download time of only 5 seconds in full resolution mode.
