Okay, seeing 3/10, transparency 5/10. First two were captured with my Borg 45ED II, 52mm ERF (i.e. 45mm effective aperture), PST etalon module plus BF10, no internal reflection for this setup, but then illumination is still uneven:
1652 (GMT+8):-
1653 (GMT+8):-
Then I replaced that ERF with my SM40, so the effective aperture is now 40mm like before... the narrower bandwidth really brought out that new active region at the limb, taken at 1658 (GMT+8):-
