Product description

This solar filter can be combined with almost all standard refracting telescopes.

Unlike other H-alpha filters, this filter has no central obstruction, which is a clear advantage in terms of contrast and sharpness.

The manufacture of this type of solar filter is therefore more difficult and expensive than filters from other manufacturers, and greater attention must be paid to optical quality and mechanical precision during production.
The result is that larger filters from other manufacturers, which cost the same or even more, cannot match the sharpness and contrast of this filter.

With a half-width of 0.7Å, it is precisely in the range where both protuberances and surface details can be seen very well.

The scope of delivery consists of a 60 mm Fabry-Perot Etalon filter with a surface accuracy of Lambda 1/100, a 20 mm blockfilter in a 2" holder for rear insertion into the telescope, and a 2"-1.25" reduction adapter.

Not included in the scope of delivery is a corresponding adapter plate for attaching the filter in front of the objective. These are available as standard for most common telescope manufacturers.

Our expert comment:

Solarscope undoubtedly manufactures the best solar telescopes and solar filters currently available.

The sharpness and contrast of these Etalon filters are impressive. This may be partly due to the obstruction-free optics, but in my opinion, it is largely due to the quality of these filters. At Solarscope Ltd., the flat discs for the Etalon are polished to 1/100 lambda – I don't know of any other manufacturer who would do this.

The large block filter (20 mm) is extremely convenient, allowing the entire sun to be photographed with a DSLR without any shadows. (Depending on the focal length of the telescope, of course).

Even though Solarview filters and telescopes are more expensive than those of other manufacturers with the same aperture, I can recommend them without hesitation. You would have to buy a much larger and therefore more expensive filter to achieve the same image quality.
