• Rig: 8" Dobsonian telescope with 20mm eyepiece (60x magnification)

Notes

The sunspot group 4079 was so large that it was visible to the naked-eye (when viewed through eclipse glasses). In a telescope the elements were clearly visible. Due to the vagaries of the atmosphere and frequent clouds, sketching was a superior (and far more enjoyable) way to record this compared to photography.
