Two sunspot groups are visible these days on the Sun, one very large and one very complex. AR 2673 is a very fast evolving region.
Setup: 115mm F/7 APO Refractor, ASI 174MM, QUARK H-alpha filter. Seeing 4-5/10. Two image mosaic.
A white light view of the groups:
And an animation showing the diference between the white light and h-alpha views:
Another interesting feature, this time on the solar limb: a large and complex, but somehow faint, prominence.
