  • 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...

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

No collimation was necessary after unpacking and mounting the instrument...

  • Implementation of UV/IR Cut Filter - Test Report

    Shooting the moon through a normal Baader UV/IR Cut Filter in comparison with the Baader IR Passfilter >>>> In the near infrared spectral range atmospheric disturbances (seeing conditions) are much more less than in the visible spectral range. Images taken in the near infrared light are often sharper than images taken in shorter wavelength. Special the moon (and the sun also) are nice targets shooting images with the IR Passfilter due to their brightness. All...
