Monster #sunspot group #AR13780 in white light and H-alpha 6th Aug 2024. #AR13781 is also in view if you expand the images, along with another region on the limb that hadn't been named yet. White light taken with a William Optics 70mm refractor, Altair Herschel wedge + Baader continuum filter. H-alpha image taken with a Coronado PST. I used a 3 x Barlow and ASI120MC camera on both and stacked the best 50% of a 1,000 frame video #Sun #ActiveRegion

Drawing of #Sunspot #AR13615, the largest and most complex white light #ActiveRegion I've ever drawn, as it looked at 11:00 UT 24th March 2024. I created it from photos taken with a #WilliamOptics 70mm refractor, Altair Herschel wedge, Celestron 3x Barlow + ASI120MC camera. #AstronomySketch #SunSketch
