Description

The artificial teeth whitening climbs through the cities is suppresses the contrast the nebulae.
The clear sky – CLS filter from TS is optimised for observation and photography of Deep Sky Objects Froms right edge Southern Spain. The artificial teeth whitening due to the cities is almost completely blocked and as the sky background and darken, whilst nebulae and star clusters retain the desired brightness. The contrast is strengthened.
The effectiveness of the filter is similar to the UHC to CLS more light breathable and so can be used even for telescopes with a 60 mm aperture.
Areas of Use
- Observation of deep sky objects with telescopes from 60 to 150 mm Lens
Astrophotography – The Brightening of the sky Hintergrundes is significantly reduced, a double the exposure time is possible.
