  • 1st Light with the QHY600 EB: a first field report

    Darkness Became Light! ... A Quantum Leap in 36 x 24mm at 61.1MP? In recent years, color cameras have become increasingly popular. A reversal of the trend is not to be expected. One reason for this is the ability to capture weak structures in deep-sky objects even with moderate exposure times. Developments in CMOS sensors and recently the BSI sensor technology have played a decisive role in this. In addition, both quantum efficiency (QE) and...
  • Field test of MaxBright® II Binoviewer by William A. Paolini

  • 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...
  • RASA 8: Test Report with mit Fujifilm X-T3 - Sebastian Voltmer

    The RASA 8 already proved itself as practical and easy to operate in the first tests. Without annoying mirror shifting I could focus the camera (Fujifilm X-T3) within one minute. Thanks to the very fast f-ratio of the RASA 8, it is even possible to focus on average bright stars in the field of view, without having to point the telescope at a bright star. No collimation was necessary after unpacking and mounting the instrument...
  • RASA 8-EXTREME: Images by Michael Jäger – with CCD-camera and f/2 Highspeed-Filter

      Before the sales launch of new high-end telescopes, the first models go to experienced testers who check them for their possibilities and weaknesses. We asked Michael Jäger, one of the most successful comet hunters and photographers, to test the RASA 8" - Rowe-Ackermann Schmidt Astrograph. Such a fast telescope with short focal length and large field of view is perfect especially for sky surveillance. Together with the telescope, Michael Jäger also received a filter...
  • The Encke Gap in Saturn’s ring system - imaged with only 17" aperture

    On 28 July 2018 around 22:00 UTC we obtained the best image of the planet Saturn so far. It was taken through the 17" Planewave Astrograph of the Rooisand Observatory in Namibia. The imaging camera was a ZWO ASI 290M with 2.9 µm pixel size. The primary focal length of the telescope was extended by a factor of 1.7 with a Baader Q-Turret Barlow lens element, the equivalent focal length was about 5 meters. A...

  • Testreport ATT 1/2018 Baader-UFC - the Swiss Army Knife of filter technology

    The current issue of Astronomy Technology Today introduces the UFC System -  the tester was impressed: What do you get if you cross an Erector Set with some giant metal washers, a plethora of variously-sized openings, a filter tray that slots in like a clip in a Glock, and, well, all sorts of other stuff? The Baader Universal Filter Changer, or UFC for short. And when Baader says “universal,” they mean it. Read the Testreport...
