NGC7331
Photo description / processing
This is the first light of a straight-through Newtonian.
The star shapes still need some work.
Currently, an off-axis guider is sticking into the aperture, which is likely causing this effect.

A question about Gain: why 140? Did you arrive at that number through experimentation?

Regarding gain, it's simpler - according to the manufacturer's specifications, it's at this specific gain that dynamic range boost occurs.
