Why choose a SkyTech DSLR Clip-Filter?
It can be inserted or removed in seconds. All lens functions (focus, preview screen, image stabilization) work as usual. If you have a telescope with short space between reducer/flattener and camera and filter wheel, or a camera lens, a clip filter is the solution. It protects your sensor from dust build-up during long exposures when the mirror is up. Why choose a SkyTech DSLR Clip-Filter?

Moonfilter for light reduction
High quality anodized aluminium, optical glass variable polarising filters for light reduction
In astronomy, polarising filters are used in various situations. A common application is the observation of reflection nebulae, where the light from stars is scattered by dust and gas clouds. A polarising filter can help increase the contrast between the nebula and the surrounding sky by reducing the scattered polarised light.
