  3. Dargestellt mit eingebautem D-ERF Filter - nicht im Lieferumfang
    From: € 400.00 Price excl. German VAT tax (19%): € 336.13
    • Filter Frame for D-ERF Filter, Diameter 75 - 180 mm
    • No serial production - every filter frame will be adapted to your needs and professionally produced on our in-house 3D-printer (70-160 mm) or are CNC machined Aluminium (180 mm)
    • Filter frame offers complete safe and firm hold for the delicate D-ERF energy reflection filters
    • Only available in combination with Solar Spectrum H-alpha Filters and D-ERF Filters

    Important note: an individual order of these D-ERF-cell mounts, which need to be specially adapted for each telescope, is always a separate production project, for which the design drawings or print data must be created in our CNC production or in our in-house design department. Unfortunately, these are not prefabricated stock products. These front filter cells are therefore not available as a standard product from the shelf or available through dealers. Unfortunately, due to the overload of our production capacity and the ongoing lack of staff in the production department, we can only manufacture such 3D-printed or CNC-turned mounts for D-ERF filters individually for new purchases of a Baader-supplied Solar Spectrum H-alpha filter in connection with a new purchase of a Baader D-ERF energy protection filter. We very much regret that we are unfortunately unable to be of assistance for other H-alpha projects.

    • The optical design places the telescope's focal point 28 mm behind the end of the 1¼" nosepiece
    • 5-year warranty if handled properly

    Please note: when using as a telecentric for H-alpha or CaK solar observation, it is mandatory to include a suitable D-ERF filter in front of the telescope aperture to prevent damage to the lens groups in the telecentric due to overheating. Heat/melting damage is not a warranty case, but only occurs due to improper operation.
