One thing that must be looked at, the QE for the Sbigs are quoted for NABG, this alone is worth 20% in QE. Do you know the correct QE for the ABG version ?.
The other thing is the debayer filters also reduces the QE by around 20%, so its really comparing chickens with ducks.
But if sensitivity is needed, then you could just use the 4x4 bin mode, and it will image in the same time as the Sbig, plus have a larger field to boot.
Remember you need to image up to 4 times as much anyway for LRGB. So you spend more time capturing images. But i know the quality of LRGB is the better of the 2 methods hands down.
But again we are talking about 2 different cameras. The color has its spot as does the Mono.
As for the camera, i am the importer and seller for the QHY series cameras in Australia, so they come straight from China to here.
You cant beat a complete 6 Mpixel cooled Color APS CCD sensor under $2,500 ANYWHERE. Closest is the SXV-M25 at $8,000.
