Products description
EXPLORE SCIENTIFIC 2" CLS Nebula Filter
The Explore Scientific CLS filter allows the precise observation of fainter deep sky targets
- High-quality Explore Scientific CLS filter
- Only transmits certain emission lines
- Absorbs almost all artificial light
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.
The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer. The CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.
The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.
SPECIFICATIONS:
- eliminates disturbing light - e.g. from street lighting
- enables observation of faint deep sky objects
