Sunspot 4420

Still growing sunspot 4420 has a 'beta-gamma-delta' magnetic field that harbor energy for X-class solar flares. As seen to me this morning through fair skies.
103mm Jagers refractor, Badder Planetarium safety prism, using neutral tensity and a solar continuum filter, Losmandy GM-8 mount. Cannon 80D camera. 650 FL 12.5 mm eyepiece. I am proud of this dedicated solar telescope as I made it myself around a used Jagers objective lens, bought on e-bay that had damaged coatings. A Moon Lite focuser, a Baader Planetarium Herschal Wedge. It has become my favorite telescope for sunspots!
