    Our most popular large camera, the STX-16803, will be retiring shortly.

    The KAF-16803 is one of the best all-round and best bang-for-buck astronomy sensors ever made. It is large, very sensitive, extremely linear, and very easy to work with - ideal for applications ranging from photometry to surveys to astrophotography. Unfortunately ON Semiconductor has decided to terminate all CCD sensor production.

    We purchased a large quantity of sensors before they stopped being available. Unfortunately we have burned through the supply more quickly than expected, and we are running out.

    If you were thinking of acquiring one of these excellent cameras, you will want to act promptly! Once our supply of sensors are gone we will still be able to build "eyeball transplant" cameras, but no new sensors will be available.

    Our replacement sCMOS camera, the Aluma AC4040, is in the final stages of testing and will be available soon. The GSENSE4040 sensor has the same physical dimensions - array size and pixel size - as the KAF-16803. It has advantages and disadvantages compared to CCD technology.

    The advantages include higher sensitivity (QE) and much faster readout.

    Disadvantages include higher "amp glow" and on-chip heating (due to millions of built-in transistors instead of a couple), fixed pattern noise, and its dual-gain 12-bit readout scheme. The dual-gain readout feature in particular means that calibration and HDR merge is far more complicated than the straightforward calibration steps used for CCD sensors. We have a new HDR merge command coming for MaxIm LT / MaxIm DL, which will be released before the camera ships. We have also added our proprietary Stack Pro (tm) in-camera stacking function as an alternative approach to obtaining high dynamic range images.

    People have been snapping up the remaining supply.

    Only one left. :(
