Details:
The sunspot AR2827 was without any special eruptions during my shooting time of 2 hours. The different brightness and sharpness reflects the variable conditions at my place during the exposure (at times cirrus clouds passed). The penumbra shows "pulsations." I don't know if this is real or an artifact due to processing?
155mm refractor, Solar Spectrum 0.3A.
