This morning, reading my emails, I notice in the Clasky Alerts a double Iridium flash ideally located: Iridium 7 and 51 will flash two minutes apart, In the head of Leo, between the Moon and Saturn (close to Mars and the Beehives star cluster). It's a very good opportunity to try my brand new Sigma 10-20 mm 1:4-5.6.
I leave home one hour before the event in order to find a good place. In the evening, I have watched for the ideally place in Google Earth. Arrived there, I must cross a dark forest to reach the Odet River shore: this site is charming!
I have decided to make two 30 s photos, in order to avoid the trailing of the stars. But I have to shot not too early nor too late (not to miss the beginning or the end of the flashes).
Once back at home, I composite the two shots in Photoshop to realize this picture with dot like stars. |
