This high quality UHC filter is a narrowband nebula filter for enhancing globular and planetary deep sky objects. It blocks out a certain band of light to enhance contrast and detail on deep sky objects.
The L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings
The Astronomik ProPlanet 642 BP is the lastest addition to the family of Astromik ProPlanet IR-pass filters. The filter thrills because of it´s wide range of applications.
The Baader UHC-S manages to improve on the contrast of the typical broadband or so-called "Deep Sky" filters. Sky background is darker, and contrast of emission nebulae are noticeably improved
The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter.
The Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard.
This Baader Planetarium Solar Continuum Filter comes in a fully-threaded 1.25" & 2" round cell. Works in conjunction with a primary white light solar filter (or Herschel Wedge Prism) to show more granulation and sunspot detail!
A unique filter for many different astronomical tasks. Incomparable in accracy to combinations of generic color filters made of raw polished glass – where surface inaccuracy adds up in the optical wave front to an unbearable degree!
More versatile than the OIII filter, the Explore Scientific 2" UHC Nebula Filter will work on a broader range of nebulous objects, due to its dual peaks in transmissions on both broader OIII lines and Hydrogen wavelengths
Planoptically polished for the highest image quality. Only 10nm FWHM with a 93% transmission rate. Perfect for planetary observation producing very high contrast levels.
