My name is Karol Novotny. I’m born 1979 in Solothurn, Switzerland. I work in an IT security company as Solution Engineer and my big passions are astrophotography and electronic music.

First, why I decided to publish this blog in English? I just want reach as much people as possible. In my opinion English is the best language for that. But my english isn’t perfect at all… Sorry if there are faults 😉

Now back to my little story: “Space-things” always very interested me since I was a kid. In 2011 I had the luck to get a telescope from a buddy. It was a Meade LX10 Schmidt-Cassegrain 8″. With it I did my first experiences in the night sky… Light pollution, alignment, star hopping… I had a lot to learn… and I still have… 😉

With the Meade I observed the most of the time Jupiter and Saturn. Saturn is my absolutely favorite planet!

In May 2015 I bought my own first telescope. And quickly I bought a DSLR for capturing these fantastic objects in the sky. This blog is my personal journal to track and share my experiences in astrophotography.

I realized very fast, the Explorer 130P is not usable for serious photography… Either I’d to buy a telescope and mount for photography and start big, or start small with DSLR lenses at less focal lengths than telescopes on a small mount.

I choosed the second option because of the financial aspect. Additional I have the possibility to walktrough the whole topic astrophotography from short to long focal lenghts.

The name star-watcher shall be a tribute to SkyWatcher, since I use their Explorer 130P SynScan and the great little red mount.

Since August, 2015 I use the SkyWatcher StarAdventurer combined with the Canon EOS 100D for all my pictures.
Since June, 2016 I use the Canon EOS 70D (as primary DSLR) and the Lacerta MGEN II Auto Guider.
Since July, 2021 I use the iOptron GEM28 mount.

Check out my mobile observatory and visit me on AstroBin or Telescopius.

Clear Skies!
