220mm mini too bright

Hi,

I know we don’t have proper astronomical nights in the UK now, but still my guiding picture seems too bright/washed out.

I use it at gain 0, at 0.5-1.0s exposures.

I have tried now fastest exposure possible with guide scope cover on now:

Doesnt it seem too bright?

are you using asiair?
I use 55 to 68 gain in phd and in the asiair 350 gain.

I notice that the guide scope needs at least 17SQM of darkness otherwise it will not see any stars. Could be it's too light there now.

4H29wipq Yes Asiair, at gain 0, f4 scope.

Is the sky dark enough at sqm 17+? This is where mine starts to 'work'.
