My best of today. Seeing was poor : average during the 10 seconds video was 2.76 arcsec according to the SSM. So:Istar Asteria TCR 8" , Baader Herschel wedge, Powermate 4x, Basler 1920-155um. Cheers to all solar observers. This sunspot group will be better in a few days :-)

You are right Bernard - emerging sunspots close to the solar limb can be quite a challenge. In my new post, Ive included H1a images which show busy prominences.
