Of the four numbered sunspots on the solar disk this morning, only two were readily seen through my equipment. But we see that, departing sunspot 4485 has a 'beta-gamma' magnetic field that poses a threat for M-class solar flares.
103mm Jaegers refractor, Baader Planetarium safety prism, using neutral density 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 Jaegers objective lens, bought on e-bay that had damaged coatings. A Moon Lite focuser, a Baader Planetarium Herschel Wedge. It has become my favorite telescope for sunspots!
