Description

What a great imaging day! I set my C8 up today to see what I could get in the one hour that the sun, at much lower altitude now, is within the gap in the trees to my south. I wasn't really expecting much since the seeing had deteriorated significantly by 1:00 PM. Am I ever glad I did! This is the best sunspot image I've ever obtained!Details:
