Description

I had the chance of a transit of the ISS on front of the Sun disc just few km from home, and no clouds! It's the first time I do this, and it was big fun! The prediction data in Calsky are very precise, so this job is not so difficult if you just plan it and get ready. I used a Lunt 60, and kept the exposure at minimum 0,1 ms. I'm surprised by the good resolution for just 60mm at least in the best frames. The image here is just the best frame with the other ISS added and one 1.6 pixel unsharp mask routine
