The Baader Visual Nebula Filter 2" O-III (4047825009357) is a high-quality optical filter designed specifically for astrophotography and visual observation of emission nebulae. This filter is crafted by Baader Planetarium, a renowned German manufacturer known for their exceptional optics and innovative solutions.
The Baader Visual Nebula Filter 2" O-III is an OIII (Oxygen III) filter, which allows only the O III emission lines to pass through, making it ideal for observing and capturing nebulae that emit light in the O III spectrum. This includes popular targets such as the Orion Nebula, the Swan Nebula, and the Veil Nebula, among others.
The filter is made of Schott B270 glass, which is known for its excellent transmission and low absorption. The multicoatings applied to the filter further improve its light transmission and minimize reflections, ensuring that as much light as possible reaches your eye or sensor.
The Baader Visual Nebula Filter 2" O-III also features a threaded 2" barrel, making it compatible with most telescopes and eyepieces. It is designed to be lightweight and compact, yet robust enough to withstand regular use.
In summary, the Baader Visual Nebula Filter 2" O-III (4047825009357) is a powerful tool for astrophotographers and visual observers alike. Its ability to enhance the visibility of emission nebulae makes it a must-have for anyone looking to explore the deep sky in more detail.
Pros of buying Baader Visual Nebula Filter 2" O-III:1. Enhances Oxygen III emissions: This filter is specifically designed to isolate Oxygen III emissions, making it ideal for viewing nebulae that are rich in this spectral line, such as the Orion Nebula, the Swan Nebula, and the Veil Nebula.
2. Reduces light pollution: The filter helps to block out unwanted light pollution, allowing for a clearer view of the night sky.
3. High-quality optics: Baader is known for its high-quality optical components, ensuring that the filter provides a sharp and detailed view of nebulae.
4. Compatible with various telescopes: The 2-inch diameter of the filter makes it compatible with a wide range of telescopes, including refractors, catadioptric, and Schmidt-Cassegrain telescopes.
Cons of buying Baader Visual Nebula Filter 2" O-III:1. Expensive: This filter is on the more expensive side, which may be a deterrent for some potential buyers.
2. Requires careful alignment: The filter requires careful alignment to ensure that it is properly seated in the telescope and is not causing any vignetting or light loss.
3. May not work well with some telescopes: While the filter is compatible with a wide range of telescopes, it may not work well with some specific types, such as refractors with a short focal length.
Conclusion:The Baader Visual Nebula Filter 2" O-III is a high-quality filter that can greatly enhance the viewing of nebulae rich in Oxygen III emissions. While it is on the more expensive side, its high-quality optics and ability to reduce light pollution make it a worthwhile investment for serious astronomers. However, potential buyers should be aware that it requires careful alignment and may not work well with some telescopes. Overall, I would recommend this filter to anyone who is serious about nebulae viewing and has the budget for it.
With a large scope, you can even view the famous 'pillars of creation' in m16 eagle. The Baader o-iii perfectly isolates two doubly ionized oxygen lines 496 and 501nm, through a very sharp narrow band pass 8. Our favorite filter for the majority of nebula, especially veil, lagoon m8, swan m17 ring m57 and dumbbell m29.
Unlike other o-iii filters, the Baader completely blocks longer and shorter wave lengths ever wonder why some filters appear red, instead of correct 500 NM teal color?. This filter has been stored in a climate controlled observatory since purchasing. For many objects, the Baader o-iii reveals a level of intricate detail that rivals best deep sky photographs. 2 NM wide, the narrowest of any o-iii filter.
It is still within the protective bag, and has no dust or other contaminates visible, which leads me to believe that never been used. Delivers the absolute highest contrast views of many diffuse and planetary nebula. The result is highest contrast achievable in an o-iii filter. Baader o-iii visual use nebula filter - 2in round mounted in virtually un-used condition, I cannot honestly tell you if have ever used this.
