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
