ISS solar transit in H-alpha

Scroll down to content

For some time now I’ve wanted to acquire images of the ISS transiting the Sun in H-alpha. Now I’ve finally took a chance and set up together with my wife the H-alpha imaging gear for just such an event. Unfortunately at the moment of the transit a “strong disturbance hit the Sun’s disk”, and made focusing almost impossible. So, only a poor image sequence was acquired. A few minutes later the seeing was quite good, but it was of course a bit too late…

Meanwhile, my wife was observing the Sun using eyepiece projection on a 127mm Maksutov telescope:
