ISS solar transit and huge prominence

This Saturday, September 24, the sun gave us another very special view, since in the southeastern limb, a huge prominence rose about 100,000 km above its surface. This fact was already a great spectacle by itself, but traveling about 65 km from my house, I could add one more ingredient, and photograph the fast transit of the International Space Station (ISS) in front of the sun.

At 12:44 pm (local time), the ISS transited the solar disk for 6 tenths of a second passing over the sunspot group AR3105 on its way.

I hope you can enjoy this wonderful scene as much as I do.

To take this picture I used a Coronado SolarMax II 90mm aperture telescope and a ZWO 183MM camera on an iOptron CEM40 mount.
