This evening we was invited for a dinner at Saltarö. It's located far away East of Stockholm and not very much light pollution.
Our plan was to use the evening to try to catch some Perseids, it's not the peak this night but good to get some practice.
|
At about 10 pm we started to setup our equipment, five cameras together.
There are clouds on the sky and that was that what the weather forecast told us too.
Even worse, there is a full Moon.
I have brought a Tokina lens with me, a 20-35 mm.
I want to test this lens as an alternative to the Zenitar 16 mm fish eye lens I normally use.
The Tokina is rectilinear which the fish eye lens is not.

This night was difficult because of the clouds, no Perseids what I could find.
But we saw two satellite flashes and one of them captured on the time lapse movie.
I'm not sure but it could be an Iridium satellite.
The time lapse movie can be found on YouTube, here: Perseids at Saltaro, 20250809.
The camera was pointed to the Zenith.

Even if I didn't get any Perseids on the photo I now know that my Tokina lens can be used in astrophoto in some special cases. |
