Scroll down to content

Decent seeing today, with some good moments. Not too much activity on the Sun these days, but it’s worth taking a shot from time to time…just to keep the eye muscles in check 🙂

Equipment: homemade 150mm F/5 refractor (ISTAR lens), 50mm ERF filter, Quark Chromosphere filter, ASI 174MM.
