Christoph Kaltseis

Christoph is not only an Adobe Photoshop specialist and as Nikon Professional touring for Nikon, but also an experienced astrophotographer. He is one of the founders of the Central European DeepSky Imaging Conference (www.cedic.at), which is held every two years in Linz since 2009.

In addition to his various projects, Christoph has developed an innovative image sharpening process called APF-R (Absolute Point of Focus)in recent years. The procedure is not always the same, but is adapted to the combination of lens and camera. Therefore, a flexible method was necessary to achieve the desired results.

In his career as an astrophotographer Christoph has also created several APODs (NASA Astronomy Picture of the Day), e.g. the APF-R-processed image of the M33 Galaxy or the Heart of the Orion Nebula (M42).

    The First Impression: RASA 8 With ATIK Horizon Colour Camera

    RASA 8 – The family is complete – First Impressions Here is a firsthand report by Christoph Kaltseis about his work with the RASA 8 and an ATIK Horizon colour camera. On the ATT fair I was asked by the company Baader if I'd like to test the newly announced RASA 8" - Rowe-Ackermann Schmidt Astrograph (#822252 € 2.195,-) . I've been using both the RASA 11" - Rowe-Ackermann Schmidt Astrograph (#822250, € 4495,-) and the larger RASA 36cm - Rowe-Ackermann Schmidt Astrograph (#822251) successfully for some time now. So I know the system of the Rowe-Ackermann-Schmidt-Astrographs very well and know the potential of these optics. So I didn't have to think twice before agreeing to a test. What can be said "Out-of-the-box" about the...

  • C14 Edge-HD f/11 with 12.000mm focal length - "Mission Impossible" accomplished?

    C14 Edge-HD f/11 with 12.000mm focal length - "Mission Impossible" accomplished?

    Theory becomes Reality! Last weekend, on the 17th of February 2019, it seems I achieved my "mission impossible". With my C14 Edge HD f/11 and the Baader FFC 3x (on a 10Micron GM 2000 HPS mount) I was close to 12.000 mm (12 meters!) focal length. Myself and Baader Planetarium optimized my C14 Edge HD to dive into this performance. It looks just like a photo: Is a 4K / 30fps video live and in real time possible? Can a sharp and bright video be achieved with a resolution of 0,21 arcsec live at my Nikon Z6 Display with full format chip (36mm x 24mm)? The answer can be found in the video. Please note the nearly complete absence of any air turbulence. This short journey across...

    APOD: M33 - Triangulum Galaxy taken with Planewave CDK14

    Impressive Image, taken with PlaneWave CDK14, chosen as APOD (27. September 2018) Convince yourself of the incredible resolution   The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp image shows off M33's blue star clusters and pinkish star...

    M45 - the Plejades taken with Baader APO and GM 1000 HPS

    The following image of the Pleiades (M45), which our customer Christoph Kaltseis has achieved with the Baader APO Travel Companion and the 10 Micron GM1000HPS on La Palma (Athos Campus), is a special treat regarding image detail and star rendition. Partically interesting is the Nikon D810A camera with a 36x24mm sensor and 4.87my pixels. Its sensational resolution will show any aberations in the optical system straight to the edges mercilessly. Most CCD cameras either have smaller sensors or much larger pixels, which helps to camouflage optical deficiencies. Not to speak of bad seeing... Image editing / sharpening was done with the APF-R Method. Due to the good optical quality of Baader APO,  airy discs with 5 micron diameter where archieved – not to mention the...
