Cheap sCMOS camera from Tucsen
A low read nose camera with scientific CMOS sensor
Today I've noticed that Tucsen - Chinese camera maker is offering a sCMOS camera Discovery C15. It's a 1270 x 1030 (color and mono available) sensor with 3.63μm x 3.63μm pixels. It offers 15fps at max resolution and low read noise - 3e r.m.s. The key feature of a sCMOS (scientific CMOS) sensor is low read noise. Not as low as in EMCCD, but still lower than in CCDs and plain CMOS sensors. Update: The color camera is named as C15 and the mono is M15.
sCMOS technology leaders (like Andor) offer sCMOS sensors with around 1.5e read noise - but at a much higher price. I found the Discovery C15 priced at $405 on alliedscientificpro.com.
sCMOS at low price could be a good planetary camera. Low read noise would give much less grainy noise - better signal to noise ratio. Mono sCMOS would be even better as it would be very handy for methane band imaging and similar cases where the planet is very dim.
On the other hand there is e2v CMOS sensor - EV76C660 that should hit the camera market later this year. The sheets state 3e read noise for it (but it's unclear if a camera would have 3e read noise in total or more). It comes in mono and color variants, and the mono has around 80% QE which is a stunning result. Solar system imaging is getting higher and higher nearly every month :)
