Review OPTOLONG Hydrogen Alpha Narrowband 12nm Ccd Filter 1.25

The Optolong Q1ha012403Y Hydrogen Alpha Narrowband 12nm CCD Filter is a high-quality astronomical accessory designed specifically for astrophotography enthusiasts and professional astronomers. This filter is engineered to allow only the Hydrogen Alpha wavelength of light to pass through, effectively blocking out other visible and infrared light.

The 12nm bandwidth of this filter ensures a high level of contrast and detail in Hydrogen Alpha images, making it an excellent choice for capturing faint nebulae and other hydrogen-rich celestial objects. The filter has a thickness of 1.25 inches, making it compatible with most 1.25-inch eyepieces and cameras.

The Optolong Q1ha012403Y filter is made from optical-grade Schott glass, which is coated with a multi-layer nano-technology coating to minimize reflection and increase transmittance. This results in a high-quality, sharp image with minimal chromatic aberration.

The filter is also coated with an anti-reflection coating on both sides to further reduce reflection and increase light transmission. The coating is scratch-resistant and easy to clean, ensuring the filter maintains its high performance over time.

The Optolong Q1ha012403Y Hydrogen Alpha Narrowband 12nm CCD Filter is a must-have accessory for any astrophotographer or astronomer looking to capture stunning Hydrogen Alpha images. Its high-quality construction, narrow bandwidth, and excellent light transmission make it a top choice for both amateur and professional astronomers.

1. High Transmission: This filter has a high transmission rate of 95% for H-alpha, allowing more light to reach the sensor.

2. Narrowband Filter: The 12nm bandwidth ensures that only the H-alpha light is captured, reducing background noise and improving the contrast of the images.

3. Compatibility: It is compatible with various telescopes and cameras, making it a versatile option for astrophotographers.

4. Durable: Made from high-quality materials, the filter is durable and resistant to damage, ensuring long-lasting use.

1. Expensive: The filter is relatively expensive compared to other filters, which may be a deterrent for those on a budget.

2. Requires Specific Setup: It requires specific setup and calibration to achieve optimal results, which may be challenging for beginners.

3. Limited Use: Since it is a specialized filter, it can only be used for H-alpha astrophotography, limiting its versatility.

If you are an experienced astrophotographer looking to capture high-quality H-alpha images, the QHY Optolong L-eNhance H-alpha Narrowband 12nm CCD Filter 1.25 is a worthwhile investment. Its high transmission rate, narrowband filter, and durability make it a reliable option. However, its high price and limited use may be a drawback for beginners or those on a tight budget. I would recommend considering your needs and budget before making a decision.

If you are a beginner or on a budget, I would recommend looking into other filters with a wider range of uses or more affordable options. However, if you are an experienced astrophotographer looking to capture H-alpha images with the best possible quality, the QHY Optolong L-eNhance H-alpha Narrowband 12nm CCD Filter 1.25 is an excellent choice.

Details:

Warning: Optolong filters are not designed for direct solar observation.

Back to top 4. 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.

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

2mm thick Scott b270 optical glass substrate material.

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

Back to top 5. 6 male filter thread no female thread, so it cannot be stacked with other filters. Non-cementing optical substrate coating.

4nm, and spectral curve transmission characteristics 90 at h-alpha line 656nm. These are not included in the item price or shipping cost.

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. This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil. 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.

Na sodium at 598nm, 589.

This can sometimes take 3-4 weeks to several countries. 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. 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 I will combine shipping weights show you discounted cost.

Optical coating specifications multi layer anti-reflection coated.

High quality protective plastic storage case.

Precise and homogeneous coatings ensure high values of desired pass band blocking unwanted offhand.

Main uses and performance suitable for viewing faint emission nebula in the h-alpha line, even full moonlight or severe light pollution. About Optolong h-alpha 12nm filter the Optolong hydrogen-alpha narrowband is designed to improve visibility of various deep sky objects.

Allowing 12nm band width of light centered on a wave length 656nm to pass through.

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