A simple tutorial


There are several ways to know in advance (even with 10 days forecasts) when and where you can catch an Iridium Flare: Heavens Above website is one of them. Surfing on it will be possible, once set your location coordinates, to know all the flares that will be visible in the following days in the selected location.

Another suggested tool is the ISS Detector app available for Android smartphones / tablets and Apple ones that offers the possibility to set automatic reminder for be sure to do not miss any flare.


The Iridium Flares are very large subjects and therefore can be photographed with relative ease. To do that it is necessary to know some simple basic rules. To be sure to take the whole event, our advice is to shoot for at least 15 seconds in a row. The tripod is therefore a mandatory tool.

We recommend to use lenses with a focal range included between 18mm and 35mm. It is possible to use also 50mm lenses even if it will be necessary to know perfectly the area of the sky affected by the Iridium and use an equatorial mount to avoid the stars trails.

Choose so the focal length based on the desired result (landscape presence or not) and your personal experience (shooting with a 18mm is simpler for sure than with a 50 mm)

Finally, set ISOs by doing some field tests a few minutes before the flare event in order to be sure of the goodness of the final result.

Use a remote shooter to avoid micro blurs.
