The sun came out after my last photo and I have had a ball! At last – I feel like I am getting somewhere with my astrophotos of the solar surface.
It turns out that it is all about the flats – get them right and the picture is magic – get them wrong and it isn’t – so I kept taking new flats in FireCapture until picture on screen lost all those Newtonian rings!
…..From photos below, you can tell I did not get it quite right with the sodium filter today!
