Baader 7.5nm Solar Continuum Filter (540nm) (various versions available)
Neue Baader Solar Continuum Filter – now with 7.5nm FWHM
Compared to the previous model with 10 nm half-band-width, the new Baader Solar Continuum Filter has a half-band-width of only 7.5 nm, which once again significantly increases the contrast. This replaces both the previous 10 nm Solar Continuum filter and, for the first time, the stacked 1¼" filter #2458392.
- Baader 7.5 nm Solar Continuum Filter, CWL 540nm
- A must for owners of achromatic refractors. This narrowband-filter cuts the spectral range where lens optics draw sharpest and contrastiest. The Baader Solar Continuum Filter lets you use the full power of your telescope.
- Enhances contrast and reduces the effect of atmospheric turbulence (in combination with white light solar filters)
- Enormous contrast gain in monochrome photography even on apochromatic systems
- Important note: The Solar Continuum Filter must be used ONLY with additional filtering (e.g. Baader Herschel prism or AstroSolar Safety Filml)
- Der Baader Solar Continuum Filter darf NUR mit zusätzlicher Filterung (z. B. Herschelprisma oder AstroSolar Sonnenfilterfolie) eingesetzt werden.

Steeldrive II motor adapter set for FeatherTouch 3.5" focuser
- Adapter set to connect the Steeldrive II Motor Unit (#2957265 , € 275,-) to the FeatherTouch 3.5" focuser from Starlight Instruments
- Allows motorized fine drive of the FT 3.5" OAZ with the Baader Steeldrive II motor unit for heavy loads (up to 8 kg)
- Please note:: The motor unit requires the Steeldrive II Controller
(#2957260 , € 445,-)
. You always need one controller to operate one motor unit. But you can use one controller with several motor units one at a time – you only need to plug it into the motor unit which you want to use.
