Details

In addition to improving the color balance, the Optolong UV/IR Cut 50,8mm filter is perfect when used with telescopes that use lens systems (such as refractors). In fact, these instruments generally work well in the visible frequencies but are not designed (except for particular cases) also for the infrared and ultraviolet. Because of this problem, the stars in the image may have a small halo. Using Optolong UV/IR Cut 50,8mm filter, this effect is eliminated.

How to use the filters:
Our filters are available in 2 diameters: 31.8mm and 50.8mm. These standards are commonly used by telescopes and their accessories. For example, depending on their function, they can be used with a CCD ora A DSLR camera (using appropriate photo adapters), but also screwed to optical accessories such as eyepieces or diagonals. Warning: 31.8mm filters do not work with 50.8mm diameter accessories and vice versa (unless there are special adapters). When you choose the version of your filter, be careful to choose the diameter compatible with your equipment.
