Daystar Quark Ha question

Daystar Quark Ha question

I have used PST's in the past and I know it is Solar minimum at the moment but I did but a Quark ha. See attached

I have it on an AltAz mount, simple to use Skywatcher rather than the heavy Evo Mount but..........

I never see granulation?????

Any ideas.

Thanks

Yes it is on for 15 minutes prior to use
