Johannes Schedler was born in 1953 in Graz, Austria, but spent his youth in a small village in western Tyrol doing a lot
of skiing and mountaineering. Since age 15 he was passionately doing chemistry experiments and electronics in his free time and after finishing secondary school studied Technical Chemistry in Graz. In 1977 Johannes developed new solutions for industrial waste water cleaning and waste gas purification and, in 1985, he co-founded the Austrian Air Pollution Control company named CTP which he currently manages.
Johannes' astronomical life started in 1997 with a simple Tasco reflector, a gift for his second son. Unfortunately, his son lost interest in the scope after a while but, fortunately, Johannes tried it out and and began to explore the Moon and the Planets. In 1998 he joined a local astronomy club and acquired a C11 on a G11 mount. Astro-related photographic film experiments failed, but in 1999 he successfully introduced a webcam for planetary imaging and motivated other colleagues of his club to do the same. Johannes' wife, Roswitha, supported his new hobby, fascinated from the endless variety of objects to observe and to image.
During the summer of 2000, Johannes built his own 3m observatory next to his home, 25 km south of Graz where he began doing digital astrophotography over the next several years with a Nikon CP995, Canon D60 and a Canon 10D. His second high quality scope was a 4” f/6.5 TMB APO refractor and finally he upgraded his digital camera to an SBIG STL-11000M.
"Ironically most times I was guiding with the C11 and imaging with the 4” refractor. I accepted the lower cost and big chip size of the Canon D-SLR with reduced efficiency, as no reasonable priced CCD cameras were available up to 2003. To overcome the low quality of these raws I tried to compensate it by long multiple exposures and tricky Photoshop processing. By doing this I was pushing the limits of digicam imaging. At the beginning of the year 2004 SBIG released the STL-11000, the first full frame CCD camera and I got one of the first models. During the year 2004 I consequently explored mainly nebulas using the wide corrected field of my TMB. Also in 2004 my wife and I did our first trip to Namibia, using most of the nights to image many fascinating southern targets with the 4" TMB and the STL on my mobile set up."
"Another dream came true in early 2005 when after a 2 years wait my 16" Cassegrain from Peter Keller was finished and installed in my observatory. This was a big step forward and allowed for imaging objects of various sizes in both medium to high resolution. The f/3 option of my Cassegrain, enables very deep imaging at medium focal length. Additionally, I am doing more and more high resolution imaging using the STL-11000 with the cassegrain f/10 set up at 4 m focal length."
In November 2005 Johannes was invited to speak at the Advanced Imaging Conference in San Jose, California where he spoke on image acquisition and processing with the STL-11000. In 2005 he also acquired a TEC-140 f/7 APO refractor with field flattener to improve the resolution for his mobile setup. This setup was used intensely for astro-imaging during his 2 week stay in Hakos, Namibia, in May, 2006. Lately Johannes prefers to take high resolution deep images of galaxies at 4 m F/L, often using the AO-L Adaptive Optics accessory on the STL-11000, taking benefit of seeing conditions less than 2" FWHM.
Johannes has had articles and images published in Astronomie heute, Interstellarum, Sky & Telescope, Practical Astronomer, and Ciel & Espace magazines. He authored the Chapter: Deep Sky Imaging with a Digital SLR, in the book, Digital Astrophotography (Ratledge David Ed.). His images have been selected for NASA's Astrophoto of the Day (APOD), in each year: 2003, 2004, 2005, 2006 and 2007.
As of this writing, Johannes observes from his home observatory at Wildon, Austria, using primarily an Astro-Optik 400 mm (16-inch) Cassegrain by Phillip Keller with corrected prime focus at f/3 and the uncorrected secondary focus at f/10 mounted on an MK 100 German Equatorial Mount (100 mm axes, 200 kg weight) by Michael Knopf/Philipp Keller, and a TEC 140mm f/7 APO refractor on an AP400 mount for mobile imaging. His main imaging camera is the SBIG STL-11000M.
SBIG is proud to welcome Johannes to the Hall of Fame and pleased to present him with our Award for Excellence in Astronomical Imaging.
