Here's a comparison of the white light view through a 4" Unitron, with Baader wedge and polariser, single 1/1000s exposure through a D810A, and a mosaic though a Lunt80mm single stack, with DMK41 and a 2.5x barlow.
AR 12443 is the long trail of sunspots.
Here's a link to a higher res version:

That AR seems to becoming more fragmented.

Good looking FDs there Andrew. Interesting pink shade on the WL, I like it.

Thanks Ted - I think it's poor selection of colour balance on my part, but this DSLR is very very sensitive to red, so I suspect I need to be a bit more careful.
