Details:
☀️ The sunspot groups AR4296 and AR4294 had reached exceptional sizes in the previous days, and they were still impressive in this White Light capture from December 8th, 2025.
The Sun was very low in the sky during this season, and imaging at 3000 mm of focal length is always challenging.
🔭 White-Light capture with Vixen VMC260L, Astrosolar ND 3.8, Solar Continuum 7.5 nm, ASI183MM.
