Sunspot group 2665 – July 11, 2017

After some time (ages actually) of “astro-inactivity” I’m slowly trying to get back at it…

After the lucky ISS transit in the morning, I’ve spared two hours for some solar imaging. A lovely giant was present on the Sun, so a few quick shots were obligatory šŸ™‚

The setup: TS APO 114mm, F/7, with the ASI 174MM camera. The Herschel wedge for White Light, and the Quark Chromosphere for H-alpha. Good seeing.

A comparison shot:
