Review OPTOLONG Hydrogen Alpha Narrowband 12nm Ccd Filter

The Optolong Q1HA012404Y Hydrogen Alpha Narrowband 12nm CCD Filter is a high-quality astronomical filter designed specifically for capturing detailed images of hydrogen alpha emission in deep-sky objects. This filter has a transmission bandwidth of 12 nanometers, which is optimized to isolate and enhance the hydrogen alpha wavelength (656.3nm) while blocking out other light pollution and unwanted wavelengths.

The Optolong Q1HA filter is made of optical-grade Schott B270 glass, which provides excellent flatness and surface quality for sharp and detailed images. It also features an anti-reflection coating on both sides to minimize light reflection and increase overall transmission, ensuring that as much light as possible reaches your imaging sensor.

The filter is designed to work with CCD (Charged Coupled Device) imaging sensors, making it an excellent choice for astrophotographers using DSLR or dedicated astronomical cameras. It has a thread size of 1.25" and can be easily attached to your telescope using a T-2 adapter.

The Optolong Q1HA filter is also coated with an IR-cut filter to prevent infrared light from entering the image and causing unwanted color shifts. This ensures that the resulting images are true-to-life and accurately represent the object being observed.

In summary, the Optolong Q1HA012404Y Hydrogen Alpha Narrowband 12nm CCD Filter is a high-performance and reliable filter for capturing stunning hydrogen alpha images. Its narrowband design, excellent optical quality, and anti-reflection coating make it an ideal choice for both beginner and advanced astrophotographers.

1. Enhanced Hydrogen Alpha (H ) Signal: The filter is specifically designed to block out light pollution and allow only the H wavelength to pass through, resulting in a significantly enhanced view of nebulae and emission objects in deep-sky imaging.

2. High Transmission Efficiency: The filter boasts a high transmission efficiency rate of 91%, ensuring that as much light as possible passes through the lens, resulting in a brighter and more detailed image.

3. Durable and Reliable: Optolong filters are known for their durability and reliability, with a multi-coated optical glass and anodized aluminum frame that can withstand harsh weather conditions and frequent use.

4. Compatible with Various Imaging Systems: The filter is compatible with a wide range of telescopes and camera systems, making it a versatile investment for both amateur and professional astronomers.

1. Limited Use: The filter is designed for H imaging and will not provide the same results when used with different wavelengths or types of imaging.

2. Higher Cost: Due to its specialized design and high-quality materials, the filter is more expensive compared to general-purpose filters.

3. Requires Specific Equipment: To fully utilize the filter's capabilities, you may need to invest in additional equipment such as a dedicated H camera or a narrowband imaging system.

The Optolong H-Alpha Narrowband 12nm CCD filter is a valuable investment for any serious deep-sky imaging enthusiast or professional astronomer. Its high transmission efficiency, excellent image quality, and compatibility with various telescope and camera systems make it a versatile and reliable tool. However, its limited use and higher cost should be carefully considered before making a purchase. If you are primarily interested in capturing stunning images of nebulae and emission objects, the Optolong H-Alpha filter is definitely worth considering.

If you are serious about deep-sky imaging and are looking to enhance your images of nebulae and emission objects, the Optolong H-Alpha Narrowband 12nm CCD filter is a great choice. Its high-quality materials, durability, and compatibility with various imaging systems make it a reliable and long-lasting investment. While the cost may be higher than general-purpose filters, the improved image quality and detail it provides can make it well worth the investment for dedicated astronomers.

H-alpha filter is the first narrowband addition to rugby set for most images who blend a black-and-white ha image into GB data enhance structural detail while maintaining natural look. Other 2 astronomy filter with standard m48x0.

Precision CBC-machined metal filter cell with sand blasted black anodized finish, anti-reflection treatment, and laser engraving. This can often change from batch to according the whims of manufacturer.

The narrowband h-alpha filter provides very high contrast to reveal subtle nebula details.

Main uses and performance suitable for viewing faint emission nebula in the h-alpha line, even full moonlight or severe light pollution. Allowing 12nm band width of light centered on a wave length 656nm to pass through.

Spectral curve transmission characteristics 90 at h-alpha line 656nm. It also blocks out infrared wave lengths 700-1100nm so a separate Ir cut-off filter is not required for imaging applications.

About Optolong h-alpha 12nm filter the Optolong hydrogen-alpha narrowband is designed to improve visibility of various deep sky objects. Non-cementing optical substrate coating.

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

Hubble look of images can be made by the combination h-alpha, iii-ccd and Sui-ccd images, such as famous pillars creation m16 eagle nebula. 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.

This can sometimes take 3-4 weeks to several countries. Precise and homogeneous coatings ensure high values of desired pass band blocking unwanted offhand.

Narrowband imaging with shoe s-ii, h-alpha, and o-iii set can be done the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks.
