Review OPTOLONG Sulfur Narrowband 12nm Nebula Ccd Filter 1.25

The Optolong SII 12nm Nebula CCD Filter with a 1.25-inch thread is a high-quality, specialized accessory designed for astrophotography enthusiasts and advanced amateur astronomers. This filter is specifically tuned to the Sulfur-II (SII) emission line at 12.0nm, making it an excellent tool for capturing detailed images of nebulae and other celestial objects that emit SII light, such as the Swan Nebula (NGC 2024) or the Eagle Nebula (M16).

The Optolong SII filter is made of optical-grade Schott glass, ensuring excellent optical clarity and color fidelity. It features an anti-reflection coating on both sides to minimize light loss and prevent internal reflections, ensuring maximum transmission of the desired wavelengths. The filter has a 97% transmission rate for the SII line, ensuring that the captured images are rich in detail and contrast.

The Optolong SII filter is also designed to block out unwanted wavelengths, such as light pollution and Halpha, OIII, and Hbeta emission lines. This helps to reduce noise and artifacts in the captured images, resulting in cleaner and more accurate data. The filter is also compatible with a wide range of CCD and DSLR cameras, making it a versatile addition to any astrophotography setup.

The Optolong SII filter is threaded with a 1.25-inch diameter, making it easy to attach to most telescopes and other optical instruments. It is also available in other thread sizes, such as 2-inch, for users with larger telescopes. The filter is also made with durability in mind, featuring a hard anodized aluminum frame to protect against scratches and damage.

In summary, the Optolong SII 12nm Nebula CCD Filter is a powerful tool for astrophotography enthusiasts and advanced amateur astronomers. Its high transmission rate for the SII emission line, blocking of unwanted wavelengths, and compatibility with a wide range of cameras make it an excellent choice for capturing detailed images of nebulae and other SII-emitting objects. Its durability and easy-to-use design make it a reliable and versatile addition to any astrophotography setup.

Its high transmission rate, ability to reduce background noise, and compatibility with various equipment make it a valuable tool for astrophotography. However, its high price point and limited applicability to other types of nebulae are drawbacks that potential buyers should consider. Ultimately, the decision to purchase this filter depends on your specific interests and budget.

If you are an astrophotography enthusiast who is passionate about capturing detailed images of sulfur emission nebulae, the QSI iNova 12nm Sulfur Narrowband 12nm Nebula CCD Filter 1.25 is a worthwhile investment. Its high-quality performance and compatibility with various equipment make it an excellent choice for those who are serious about astrophotography. However, if you are a beginner or have a limited budget, you may want to consider other options that offer a more balanced performance in various types of nebulae.

Details:

Allowing 12nm band width of light centered on a wave length 672nm to pass through, which corresponds sii emission lines. 25 Optolong sulfur ii s-ii narrowband 12nm nebula ccd filter will combine the shipping weights and show you discounted cost.

Precise and homogeneous coatings ensure high values of desired pass band blocking unwanted offhand. Warning: Optolong filters are not designed for direct solar observation.

Very high surface quality of or better us military spec mil-o 6nm, transmission major lines artificial light pollution: Hg mercury at astronomy filter with standard m28.

2mm thick Scott b270 optical glass substrate material. Na sodium at 598nm, 589.

Precision CBC-machined metal filter cell with sand blasted black anodized finish, anti-reflection treatment, and laser engraving.

High quality protective plastic storage case. 4nm, and these are not included in the item price or shipping cost. Optical coating specifications multi layer anti-reflection coated.

Back to top 5. Back to top 3.

Non-cementing optical substrate coating. Ultra-thin filter cell to minimize vignetting clear optical aperture of 26mm. Back to top 4. Hubble look of images can be made by the combination h-alpha, iii-ccd and sii-ccd images, such as famous pillars creation m16 eagle nebula.

This can often change from batch to according the whims of manufacturer.

It also blocks out infrared wave lengths 700-1100nm so a separate Ir cut-off filter is not required for imaging applications.

Spectral curve transmission characteristics 90 at sii line 672nm.

This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil. Electron-beam gun evaporation with ion-assisted deposition coating technology for durability and resistance to scratching, as well stability on cowl central wave length so that there is no deviation due temperature changes during use.

6 male filter thread no female thread, so it cannot be stacked with other filters.

It does this by: selectively reducing the transmission of wave lengths light pollutants, specifically those produced by artificial lighting including mercury vapor lamps, both high low pressure sodium lights, and unwanted natural caused neutral oxygen emission in our atmosphere. Narrowband imaging with shoe set can be done the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks.

Main uses and performance use with h-alpha iii-ccd narrowband filters shoe set for tricolor ccd .

Technical specifications both surfaces are fine optically polished, accurate to 1/4 wave length or better, and parallel within 30 seconds arc.

This can sometimes take 3-4 weeks to several countries.
