8th September, sunpot on a spotless day

Post by robert » Sat Sep 08, 2018 1:56 pm

I was expecting a spotless sun but as the seeing was ok and I tried the Newtonian 200mm for granulation in white light. I was amazed to see a group of small spots. I did a CaK FD to locate them and a cropped view in CaK to compare.
