BTS - Sunset With Sunspots

Here's a behind the scenes photo from when I was shooting the sunset the other day. The little blue box on top of the telescope is the camera, a monochrome camera with a resolution of 1024 x 768 pixels.

I sat in the shadow beneath the stand to better see the computer screen and be able to monitor the recording. In this picture, I've embedded a actual screenshot from the original movie onto the computer screen to give you a fell of how it looked.

As you can see, the camera was somewhat tilted and not aligned to the horizon, so that has been corrected in post production. Also, since using a diagonal mirror on the telescope, the Sun is moving in the "wrong" direction in the recorded material, so that also needed to be fixed. The last thing I did was to add a yellowish color to the Sun to make it look like we're used to see the Sun.

The original movie is 17 minutes long and shows the entire sunset. In the final movie I've just used 5 minutes where the Sun is passing behind the radar tower and speeded the movie up 5 times to save you guys some time :-)

Uppsala Amatörastronomer

De senaste två dagarna har jag varit i Uppsala och besökt Uppsala Amatörastronomer (UAA - http://uaa.saaf.se). Många teleskop att titta på och många samtal om astronomi, utrustning och fotografi. Andra kvällen höll jag ett föredrag om mitt fotograferade i deras klubblokal. Ett riktigt givande och kul besök och jag har lärt känna många nya vänner.

The past two days I've been in Uppsala visiting Uppsala Amateur Astronomers (UAA - http://uaa.saaf.se). Several telescopes to look at and a lot of interesting talk about astronomy, equipment and photography. The second night I held a lecture about my work in their clubhouse. For me it was a very enjoyable visit and I got to know many new friends.
