Many frames can be averaged together to average out the light levels, but each frame contains this noise, so the effect is to average out the noise, not to remove it. With Pix Cellent a very small amount of noise is added on read-out, but the signal is building up on the CCD for the full integration time. This process is much more efficient at producing a high signal to noise ratio imaging than adding noise and then averaging. Pix Cellent cameras can be split into two main generic types, An tares and Cap ella . The An tares cameras are the highest performance imaging systems available.
Slow scan read-out electronics ensure the lowest noise possible.
For the ultimate in sensitivity long exposures are required, necessitating cooling of the CCD by Peltier or liquid nitrogen. The Cap ella cameras also use very low noise electronics and cooling to minimise dark current, but are faster than the An tares . Read out speeds offered are 500kHz, 1MHz, 2MHz, 4MHz, 5.5MHz and for some CCDs 8MHz. Fully flexible binning is available at 500kHz, 1MHz and 2MHz. Most definitely yes.
