My name is Alexander Forst, and I am a photographer from Berlin, living in Switzerland for 8 years now.
Some years ago, I decided to step up my night sky game and modify the sensor of my camera. The modification expands the light spectrum, which makes it possible to see the Ha emission nebulas in the night sky.

I love stories and I love telling them using my pictures. However, the reason why I started photography was that I just wanted to take some good selfies. I still take selfies but nobody will recognize me there. Photography has become a lot more for me than a means to an end. It is the expression of my art, my feelings, and my fantasy. Since I can remember I love the stars and it was only natural to start with star photography.
My inspiration comes mostly from movies and also computer games. I don't take inspiration from other photographs that often and I cannot really tell why, but I think maybe because it is easier to get a story and a feeling from a movie or a game than it is from stills.
why this picture has the same sky as another one? literally the SAME: same star luminosity, same position... and same cloud! That's not fair when you only said "modify the sensor of my camera. The modification expands the light spectrum, which makes it possible to see the Ha emission nebulas in the night sky": that's not the truth, you photoshopped some picture. for example: DSC5810-HD..._880-1.jpg 
VERSUS DSC4571-Be..._880-1.jpg

Star photography requires a lot of patience. You need to plan everything beforehand. Everything has to be perfect. The location, the weather, the motive and the direction of the sky. But it's not only that. My pictures become more and more complex, so sometimes, it takes hours, even days, to edit a single photograph to get it just right. But the end result is always worth it.

Eplaining of the Exifs: Stacked: Multiple shots overlayed for Noise Control and increasing details. Tracked: The Camera was standing on a device which rotates syncron with the stars. Blended: The shots where taken from the same Tripod location. Composite:: The shots where not taken from the same tripod location. Single: A single image. braketing: different exposure times for brighter lights
