The bright thing in the sky appeared again. So I shot it.

Trying avistack for first time today so both stacked by it. Wavelets applied in Registax 5.1, finish in PSE9. Both files were just over a minute for over 1000 frames each. I have no idea what I'm doing in avistack but have now found the full auto mode. That'll do for now! This is now my best ever detail level in H-alpha.
Still got a LOT more data to go through! Will concentrate on the Ha data, due to field of view limits with the barlow, I have to do the sun in two halves. So I've got two sets for prominences and another one for surface to go, then the nightmare of blending it that I never got working well... The CaK data still isn't sharp... in part this might be reaching the limits of the 100-400L and I need to get a bigger scope on the job, once I've ordered the appropriate mounting bits.
