Sunspot group 2665 – July 11, 2017

Posted in ASTRO, Uncategorized on July 11, 2017 by maxpho

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 🙂

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:

ISS and a sunspot

A lucky transit of the ISS occurred over my home. Only a fast setup of the astro gear was required for this event.

The large AR 2665 sunspot group added the already interesting view.

Equipment: 127mm Maksutov, full aperture solar filter, H-alpha 35nm filter, ASI 174 MM camera.
