Sonnenbeobachtung

Solar observation is a very interesting area of Astronomy. There is something new to see here practically every day. Our home star is constantly changing! Regardless of in white light or in the narrow-band hydrogen or calcium band, observations of the processes on the sun are very impressive!

ArteSky Energy Rejection Filter (ERF) 240mm

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.

Diameter (mm): 240
Thickness (mm): 15mm
Surface shape: L/4
Centre wavelength (nm): 656.28
Bandwidth (nm): 60
Peak transmittance (%): 95%
Cut-off range (nm): 200nm-1100nm

Baader 7.5 nm Solar Continuum Filter (540 nm) - 1.25" Filter Thread

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)
