Omegon Blocking Filters 1.25'' UV/IR Cut Filter
Omegon IR/UV blocking filter - keeps your images of your planets sharp
Truly sharp planetary images are only possible using an IR/UV blocking filter. This Omegon filter only passes visible light between 400 and 680nm. The UV and IR regions of the spectrum are completely blocked.
CCD exposures of planets and stars: sharp images
A CCD camera is not only sensitive to visible light but also to other wavelengths. The planets not only shine in visible light, but also in the infrared, for example. But they are out of focus in the IR region. Omegon's filters only let through visible light, the light that was really 'wanted', ie sharp planetary images.
Solar Observing: Blocking UV Light
Omegon's UV/IR blocking filter is also very useful for observing the sun. Harmful UV rays that can contribute to cataracts are filtered out. The filter is also essential when using a Herschel wedge, but is also extremely useful when observing using an objective solar filter (eg a sheet filter).
Your eyes are valuable! - protect them with an Omegon UV/IR blocking filter.
