I had a brief moment of clear seeing on the morning of the 30th June & quickly setup in my front driveway to capture the Sun, with AR2835 dominating the activity.
There was not have time to check focus / adjust etalon filter, as I got 1500 frames before the clouds rolled in and stayed overcast the entire day, so happy things seem to have been set right from the last imaging session.
