Dear fellow night-sky explorers,
I have been keeping an eye on CMOS developments and have noticed that a few days ago Sony released a new 12mp sensor - IMX253.
Unless I am reading the specs incorrectly, the new CMOS sensor seems to be significantly more sensitive than ICX814 (915mV vs 660mV at F8), in spite of having a tad smaller pixels than the above mentioned CCD sensor (3.45microns vs 3.69 microns). I know that ADC is only 12bit and that the pixels are tiny, but if read noise is low then perhaps things are developing in the right direction?
