Frejvall's Astro Site

Welcome to my Astro Adventures!

I live Saltsjöbaden, South-East of Stockholm, and have done that since 1970. Immediately when my family moved here I noticed that the Stockholm Observatory was on a hill just a few hundred meters from our home. I didn't hesitate. The professors and researchers at the observatory were visited by the 12-yearold and after a while I was even out there at night helping out with this and that. The observatory houses a twin-barrel refractor of 400 and 600mm apterture, a 1m Schmidt, a 1m relfector, a 400mm astrograph and a couple of old small instruments.

The hobby lived on through the school years and I had my own keys to the Observatory until the early nineties. After that it sort of died out. Now, since 2009, I am completely and utterly trapped in the fascinating field of astrophotography. The equipment is piling up and I do most of my testing and some work from a pier on my balcony, and since 2013 I have a fully automated remote observatory in the mountains of Provence.

Having worked for 36 years with electronics and software development as well as general IT systems, the modern world of astronomy is truly a good fit for me. On this site I try to present my ideas, my stuff and the software and hardware I develop in order to get hte most out of my astro hobby.

I do not have any eye-pieces for my telescopes. Well, actually I have a few, but I never use them. My telescopes have CCD cameras and I concentrate on getting images instead of observing. Since 2012, my main interest is unguiding imaging with encoded mounts and the technology that surrounds this. 90 percent of the images that fly past you at the top of this site were shot unguided, one was guided. Naturally, all images are by me.

Browse around, try my software and meet me at Progressive Astro Imaging, Stargazers Lounge or Cloudynights under the username "perfrej".
