White Light group
In the SM60 with the 15plossl, the main part of the group shows the two dark umbra areas and a lot of twisted disturbances around it.
In white light, JMB filter on the ED80, 10.5plossl the separate two areas are well seen. The larger "spot" breaking down into two separate areas, which large. The secondary distrubed area shows to have an umbra area, and between the two are a couple of small spots!
So even in white light it looks interesting with 6 umbra areas visible.
Good practise for solar observers!!!
