A clear day today but the air was rough due to wind. These single exposure images taken with a Canon 550d camera show the southern hemisphere of the Sun with AR 2795 and 2794.
First two images are at Ha wavelength thru a Lunt 100 Ha scope, the third is thru a WO 81 mm scope with herschel wedge at 540 nm showing the sunspots.

Well done John.
Nice captures there.
Was clear down here (for a change) but spent too much time working with a recalcitrant Spectroheliograph!!!!
A nice set of images John. I especially like the way you have captured surface features and prominences in Ha. Well done.
