One trouble is tho, although it red sensitive, most red nebulas are excited by bright star/s which are usually in the same field of view, and make it bloom heavily in LRGB. As Fred said its a narrow band weapon.

I was considering one of these cameras as well. Steve Crouch makes good use of his so the blooming can be controlled. Shorter exposure times in LRGB imaging would be the go to control the blooming and high cooling to reduce noise so stacking does not add too much noise.
Highish QE and high well capacity with largish pixels is a good formula there. Too bad the antiblooming version dropped so much in QE and is no longer made.
