  • HALOS – viewed without prejudice

    The moment you insert any type of filter into the optical setup, which consists of your specific camera, the appropriate flattener/reducer or coma corrector and the telescope, the filter becomes part of this unique optical system. And every optical system is different because many products from different manufacturers are involved. All optical surfaces interact with each other in some way. One possibility is that coatings of the camera reflect unwanted light back into the telescope...

  • RASA 8-EXTREME: Images by Michael Jäger – with CCD-camera and f/2 Highspeed-Filter

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...

  • Baader Universal Filter Changer (UFC): Simple photographic use example (Part 7)

    We've been asked a few times recently on how to set up the Baader UFC for use with a DSLR and a range of wide-field imaging refracting telescopes. So we thought we would write a short blog on some ways this can be done. Let us start from the telescope side first. All the enquiries we have had, the wide field refractors have 2" barrel focusers, so there is our starting point. The telescope side...
