Transparency 7/10, seeing 2-3/10, sun activity low.
First of all, two shots to compare the effect on the Tmax, both acquired by SM40/BF10/Borg 45ED II at prime focus:-
1509 (GMT+8), optimized for the QRF near the bottom:-
1512 (GMT+8), optimized for even illumination:-
Notice that some surface contrast is compromised if we opt for even illumination.
A prominence only shot at 1513 (GMT+8):-
Double stacked with PST etalon, 1518 (GMT+8), seems like it's the best of both world, you got a prominence extended all the way into the solar disc as a QRF, illumination is quite even, too:-
The b/w version shows better how the prominence and the QRF are indeed one, it's also orientated like the first two:-
Finally, I did a shot soon after sunset, it shows the color of the sky, the moon and Jupiter, plus an aeroplane trail, click for full size:-
