Solar Na (D1) and CaK 12Oct 21

The large well formed sunspot (AR2882) dominates the surface.
The MiniSHG captured in Na(D1) and H alpha before the seeing collapsed(!!!)
The WL with the Genesis at f13 were hopeless due to seeing....

The CaK image was earlier with the 90/1100 and DIY filter.
H alpha to follow (some neat proms!)
