A lot of CMOS sensors have Amp glow but some of the higher end Sony CMOS sensors don’t. Many of the CMOS sensors that are picked up come from video applications where amp glow is of little consequence; take the IMX183 as an example.

The exposure time required is a consequence of pixel size, focal ratio and read noise. Low read noise, large pixel on a fast telescope (thinking GSENSE-6060) you can potentially get away with 30s exposures and being read noise limited with narrowband.
