I use APT / Astrophotography Tool
- latest ZWO ASCOM driver
with ZWO ASCOM driver one can use one of the presets or Adv. / manually: gain 100, Offset 50
the resulting offset is 1 (!)
logfile extract after bulb shoot for Flat
when using APT + the ZWO ASCOM driver I get:
Exp 1/25 : Bin(1x1), Gain(100), Offset(N/A), Duration(0.53") Filter(Antlia DNB) CCD T(21°C)
The FITS header readout shows offset values of 1 or -1 (!)
update:
the ASCOM driver doesnt support offset (in my setup), the native driver does support offset.
