ISS transiting the Sun – June 30th, 2014

After a very long period of no transits of the ISS over the Sun, I have finally got a chance of perfectly clear skies and a close flyby of the ISS at around 470km. Together with my wife I drove a few kilometers from my workplace and settled into a corn field at 30 degrees Celsius. When the moment came we’ve both pushed our remote control buttons and got the dark silhouette of the ISS close to the freshly emerged sunspot groups 2104 and 2107.

The equipment: 90mm Maksutov and Canon 550D  at 1/2000s and ISO 100 for my wife, and a 115mm at f/18  APO Refractor and Canon 550D at 1/3200s and ISO 100 for me. Both with Baader solar filters (of course) on EQ-6 and EQ-3 equatorial mounts. Data for the transit were, as always, calculated for us via CalSky.
