Description
It reduces the brightness of the moon and thus enhances the contrast in the observation. This filter is mainly necessary during the major moon phases, since the subjective glare of the moon then is strongest and can quickly become unpleasant.
More than a normal moon filter
However, the filter doesn’t only offer advantages during lunar observation, but it also allows forhigh contrast observations of planets.It amplifies the surface details that make observation particularly interesting. The filter is most strong in the red / blue range. Thus, objects such as the ‘Great Red Spot’ and the bands of cloud on Jupiter appear clearer.
A particularly disruptive factor during observation is the illumination of street lights. This is blocked in the conventional spectral range so that high-contrast observations are possible.
This premium moon filter is much higher quality than similar products
There are some cheap offers in this field where the image quality of the telescope suffers due to the filter. This premium moon filter, however, is characterised by very good characteristics.
