The following images featured were taken through 3 telescopes.
Hydrogen Alpha images were single stacked through a 60mm Coronado Solarmax II. Cak was taken with an Orion ED80 CF Triplet, while the white light close up of AR2781 was imaged through a C11 on Nov 7 in average seeing.

Gerard,
Well done mate!
Your images are very good, I'm impressed.
Hopefully you'll continue to record this impressive AR for the next few days.

Super impressive work there.

I want to get into some white light imaging, I have a solar filter for my 6" SCT, what's the best time of the day to image the sun?

Thanks for posting, Andrew

Andrew,
The seeing conditions are usually better in the morning - more stable air.
Observing away from concrete/ road surfaces also helps. These heat up, retain the heat and cause local disturbance.

Thanks for your kind comments guys. As far as taking another look at this AR is concerned my prospects look bleak until at least next weekend.
Andrew, as for the best time to observe, I would go with Ken's comments and try to stay clear of iron and cement surfaces that radiate a lot of heat.
Good Luck
