Review ORION extra Narrowband Sulfur ii Imaging Item

The Orion 05579 Orion Extra Narrowband Sulfur II Imaging Filter is a specialized accessory designed for advanced astronomers and astrophotographers seeking to capture high-quality narrowband images of celestial objects, particularly those emitting Sulfur II emission lines. This filter boasts an ultra-narrow bandpass, optimized for the Sulfur II emission line at a wavelength of approximately 672.4 nm, which makes it an ideal tool for imaging various nebulae that exhibit strong Sulfur II emission.

Crafted from high-quality optical glass, this filter boasts a transmission efficiency of up to 85% within its narrow bandpass, allowing for maximum sensitivity and signal collection. Its extra narrow bandwidth, combined with its high transmission, enables the capture of intricate details and subtle nuances that would otherwise be lost in broader bandpass filters.

The Orion Extra Narrowband Sulfur II Imaging Filter features a 1.25-inch diameter, making it a perfect fit for most popular telescopes and imaging systems. Its robust, yet lightweight design ensures durability and ease of use, making it a reliable companion for extended observing sessions.

This filter is coated with a multi-layer, enhanced reflective coating, which minimizes light loss and interference, ensuring the purest possible signal is transmitted to your imaging sensor. Its anti-reflection coating on both sides further reduces unwanted reflections and stray light, contributing to a higher contrast image.

The Orion 05579 Orion Extra Narrowband Sulfur II Imaging Filter represents a significant investment in advanced astrophotography equipment. Its exceptional performance and unparalleled ability to reveal the subtlest details of Sulfur II emission nebulae make it an essential addition to any serious astronomer's or astrophotographer's arsenal.

Orion's 05579 Orion-Extra narrowband SII Imaging Filter-1.25 is designed for astrophotography enthusiasts who specialize in narrowband imaging, specifically for the Sulphur II emission line. Here are some pros and cons that might help you make an informed decision about purchasing this filter.

1. High Transmission: This filter allows a significant amount of light through the Sulphur II emission line, making it ideal for capturing detailed images of emission nebulae.

2. Low Dark Current: Orion's Orion-Extra filters are known for their low dark current, which results in fewer electronic noise artifacts in your images.

3. Multi-Coated: The multi-coated glass ensures that as much light as possible passes through the filter while minimizing reflection and scatter.

4. Suitable for CCD and DSLR cameras: This filter is compatible with both CCD and DSLR cameras, catering to a wide range of astrophotography enthusiasts.

5. Thin Design: The 1.25" thickness makes it easy to use with a variety of telescopes and mounts.

1. Specific Application: This filter is designed for astrophotography and specifically for the Sulphur II emission line, which may limit its versatility for other applications.

2. Cost: Narrowband filters generally tend to be more expensive than their broadband counterparts due to the specific materials and manufacturing processes required.

3. Requires a Dark Sky Location: To capture high-quality images with this filter, it's essential to have a dark sky location with minimal light pollution.

Orion's 05579 Orion-Extra narrowband SII Imaging Filter-1.25 is a high-quality tool specifically designed for astrophotographers focusing on the Sulphur II emission line. Its advantages, such as high transmission, low dark current, multi-coated glass, and compatibility with both CCD and DSLR cameras, make it an excellent investment for those pursuing detailed images of emission nebulae. However, its specific application and higher cost are important factors to consider before making a purchase.

If you're an astrophotography enthusiast with a strong interest in narrowband imaging and capturing detailed images of emission nebulae, Orion's 05579 Orion-Extra narrowband SII Imaging Filter-1.25 is a worthwhile investment. Ensure that you have a dark sky location and the necessary equipment for astrophotography before purchasing.

Details:

The extra-narrowband false color images, while beautiful, also reveal much about the chemical composition of nebula and its various features. Images taken with extra-narrowband filters typically look much different from those acquired using standard true color RGB methods. By imaging with the Orion S-II, O-III, and H-alpha extra-narrowband line filters. This is the approach used by astronomers for many of nebula pictures taken with Hubble Space Telescope.

Now you can capture dramatic Hubble-like CCD images of emission nebula's from the heart city or under a full Moon. The Orion S-II filter passes light at the 672.4nm wave length the Sulfur-II line in deep red end of visual spectrum with very high 90% transmission and a band pass 7nm. These specialized filters transmit only the specific wave lengths of light that are important in emission nebula's, while blocking out all other light, whether artificial or natural - from street lamps, Moon, you name it. Includes protective plastic case.

Each filter is held in an anodized aluminum cell that threaded to fit a standard CCD camera 1.25 nose piece or Orion multiple wheel. All three are par focal, meaning no refocusing is needed when switching among them. The result: high-contrast tricolor images from even grossly light-polluted skies. It complements Orion H-alpha and Oxygen-III extra-narrowband filters, which together allow advanced tricolor imaging of emission nebula's with monochrome cameras or similar.
