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 Explore Scientific H-beta filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colors, the so called emission lines. Those emission lines are linked to chemical elements - in this case hydrogen.
The Astronomik UHC is THE filter for visual observing. You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers.
This is a small accessory pack put together by us to compiment first time GOTO telescopes. The kit comes with a 12v mains power supply, a 40mm wide angle super plossl eyepiece, an Antares ND25 moon filter and a Philip's Planisphere to find objects and learn about the sky
From the start, the Astronomik OIII filter has been very specifically designed for the visual observation of gaseous and planetary nebulae. The extremely narrow pass band of the two OIII lines brings a substantial contrast gain
CCD imagers will find Baader's new Narrowband CCD pass filters to deliver the absolute highest contrast deep sky images in H-Alpha, H-Beta, Oxygen III, and Sulfur-II, with the shortest exposures possible.
