Stu, this is great!
I understand correctly that you are using DS, if this is, how it is implemented?

You lucky piglet Stuart!! I saw that crack of sunshine hovering over you all day today. We were just on the edge and it never got here until 3pm when the Sun had gone out of my viewing window. Not envious in the slightest, honest :lol:

Tremendous images by the way :bow :hamster:

Hi Ivan,
Yes, it’s double stacked. I have two Lunt 35 etalons working in tandem on the rear of my scope behind a Barlow that makes the light cone substantially parallel and feeds this into the etalons. There’s a refocusing lens behind the etalons to bring the Sun back into focus on the sensor.

Ha…ha…it makes a change for Preston to get the Sun. As I say, you’re always welcome here.

I struggled to get these images any sharper today for some reason.

Stuart,
Your images mirror Pedro's very closely. Very similar in detail and quality. The features have changed little also.

Excellent contrast and detail.
