After that I’ve added more and more optics. So I was able to work with the Celestron optics at almost 4000mm focal length with the mount doing all the work to compensate for Earth's rotation. I got really good at it and kind of became an ambassador. In 2015 I’ve started using high-tech mounts from 10Micron through the distributor Baader Planetarium. Since when have you been professionally involved in astro photography? Christoph: The subject of astronomy has always been a part of my life since childhood.
PI: That puts you right in the PRO range. Those two are some of my absolute favorites as well.
PI: What equipment did you use to take these pictures? Christoph: For the photo of M 101 I’ve used the Celestron RASA 36cm 792mm f2.2 and for the photo of M 33 the PlaneWave CDK 14 2536mm f7.2. At the 7 o'clock position from the center of M33 the brightest star forming region NGC 604 is also visible. This sharp image shows the blue star clusters and pink star forming regions along the loosely wound spiral arms of the galaxy. With a diameter of over 50,000 light-years, it’s the third largest galaxy of the local group after the Andromeda Galaxy and our own Milky Way. M33 is located in the small, northern constellation Triangulum and is about 3 million light-years away from our Milky Way. What makes it so special? Christoph: The population of well-measured variable stars of M33 has helped make this nearby spiral a cosmic benchmark for determining the distance scale of the universe. PI: With up to 45,000 daily image submissions, the following image of yours was also named "Astronomy Picture of the Day". Along its magnificently designed spiral arms are the blue colors of hotter, young stars mixed with concealing dust trails and pink star-forming regions. Its core is dominated by the light of cool, yellowish stars. The colors of the Milky Way stars are also found in the starlight of the great island universe. In addition to M101, we also see more distant background galaxies, foreground stars within the Milky Way and the companion dwarf galaxy NGC 5474, visible in the lower right. With a diameter of about 170,000 light-years, this galaxy is not only beautiful but also huge, almost twice the size of our own Milky Way. What does the first one show? Christoph: The photo shows the spiral galaxy M101, which lies within the boundaries of the northern constellation Ursa Major, about 23 million light-years away.
Your astro images are very successful and are regularly chosen as "Astronomy Picture of the Day". I haven't been able to get away from it since. When I got the book for the series, the pictures fascinated me so much that I wanted to do something like that myself. How did that come about?Ĭhristoph: At the age of 5-6, space captivated me through the television series "Cosmos: A Personal Voyage". PI: Hi Christoph, you have been in the photography world for many years, have made a name for yourself as an astrophotographer, you work as an ambassador for well-known companies and you’ve initiated many interesting topics in the industry. Today Christoph will talk about his experience in astrophotography and reveal the tricks he uses to get the finest details out of his stunning images.
The plugin has already proven many times that it can meet even the high quality standards in astrophotography. The tool sharpens images using APF-R with just a few clicks, even without much prior knowledge. We have now developed the easy-to-use APF-R Photoshop plugin for Christoph's complex process. The Hubble Space Telescope team has been using his method for over 2 years. In recent years, he has developed APF-R (Absolute Point of Focus), an innovative image sharpening process in Photoshop that has attracted considerable interest among experts. The secret behind natural looking, fine resolution deep sky images "Even the Hubble Space Telescope teamĬhristoph Kaltseis is a Photoshop expert and an experienced astrophotographer.
