Compared to my FSQ the AP130 has 60% or so more flux collection and is faster, running at f4.5...hence not too hard to harvest photons without
the heroic exposure times.

Thanks Peter,
I'm a bit confused by what camera you used?
Your info at the bottom of the pic -
"SBIG FW7-STX AstroDon 5nm Ha 3nm OIII"
refers to a filter wheel - not a camera.
Was it your new QHY600?
cheers
Allan
