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 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 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.
Observing difficult, dim Deep Sky targets like Planetary Nebulae and certain supernovae remnants, such as the Veil Nebula in Cygnus from light poluted environments can be a very tricky business. This is where the Explore Scientific 1.25" O-III Nebula Filter shows its strengths.
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!
The ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras and offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.
Planoptically polished for the highest image quality. Only 10nm FWHM with a 93% transmission rate. Perfect for planetary observation producing very high contrast levels.
The Astronomik UV-IR Blocker is the ideal choice as a luminance filter for any kind of digital photography. Now available in the popular Canon EOS Clip Fit.
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.
An Ideal filter for sun and Moon observation and contrast enhancement in planetary observations. To screw into any 1¼" - or 2" eyepieces - for example the Baader Herschel prism (#2956500P or 2956500V)
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
The Optolong CLS (City Light Suppression) broadband filter is designed to improve the visibility of various deepsky objects by selectively reducing the transmission of wavelengths of light pollutants
