After the Ha imaging I moved to the AT80EDL for some WL imaging. Used the Lunt wedge, and both the UV/IR cut and Ultrablock filters. Best focus was a guess given the seeing. First up, a full disk shot, compared against the SDO HMIIF image:

34s video, 30 fps @ 1/160 ss, 25% stacked.

 

LOTS of tiny spots scattered across the disk.

 

I then added a 2X Barlow to the optical train for these zoomed-in images:

Images from the green boxes are just digital enlargements of the original zoomed-in shots. Multiple light bridges can be seen.

Thanks Warren! These groups may not look like much from a FD viewpoint, but they have a lot of complex detail.
