Solar ha - no detail - could focuser alignment be a factor?

Recommended Posts

As reported in a separate thread (thanks to Charl for his response), I could see no detail on the sun's surface today (through Lunt LS60 with double stack filter) apart from the new spot - which I initially put down to bad seeing. So I packed up. Only then did I see that the Steeltrack focuser (carrying heavy Baader MkV binoviewer) was slightly misaligned, with one of the attaching grub screws coming loose. By this time clouds had covered the sky so I wasn't able to continue viewing - but I'm wondering if the lack of detail was down to the focuser - misaligning with the blocking filter? There are much more knowledgable solar ha people on this forum than Me - wonder if there's any truth in my theory?

I would not have thought so unless it was wildly out.

I tune single stacked then add the D/S and tune to get best view then normally a tweak is needed on the single stack just to bring it to the best image .

Yours maybe different as my setup is a combination of Lunt and coronado kit.

 

seeing can make a huge difference.
