Accessories for solar observation (optical)
Here you can find all the accessories with which you can equip, upgrade and add to your telescope.
Energy protection filters are long-pass filters that block short-wave light. A coating blocks IR. This means that the filters of an H-alpha telescope are only exposed to red light.

- Centre wavelength (nm): 656.28
- Bandwidth (nm): 60
- Peak transmittance (%): 95%
- Cut-off range (nm): 200nm-1100nm

The Baader Solar Continuum Filter is practically a narrowband photosphere filter for solar observation in white light and provides the highest contrast.
- Baader 7.5 nm Solar Continuum Filter, CWL 540 nm, in cell with 1.25" screw-in thread
- A must for owners of achromatic refractors. This narrowband-filter cuts the spectral range where lens optics draw sharpest and contrastiest. The Solar Continuum Filter brings power back to you.
- Enhances contrast and reduces the effect of atmospheric turbulence (in combination with white light solar filters)
- Enormous contrast gain in monochrome photography even on pure color systems - see second and third image
- Important note: The Solar Continuum Filter must be used for purely VISUAL solar observation ONLY with additional filtering (e.g. Baader Herschel prism or AstroSolar Safety Filml)
