Review OPTOLONG Pro Deep Sky Filter Light Pollution Reduction

The Optolong L-Pro Light Pollution Reduction Filter is a high-quality astronomical filter designed to significantly reduce the impact of light pollution on your night sky observations. This filter is specifically engineered to block out the harmful light emitted by streetlights, city lights, and other artificial sources, allowing you to see deeper into the night sky and observe fainter celestial objects with greater clarity.

The Optolong L-Pro filter utilizes a sophisticated optical design that features multiple layers of high-density optical glass, each coated with a unique mix of nanometer-thin dielectric materials. This multi-layer coating is designed to reflect specific wavelengths of light, while allowing other wavelengths to pass through unimpeded. The result is a filter that allows you to see the night sky as it was meant to be seen, with rich colors and sharp details.

One of the standout features of the Optolong L-Pro filter is its ability to block out a wide range of light pollution wavelengths, including sodium, mercury, and high-pressure sodium streetlights. This means that even in areas with heavy light pollution, you can still enjoy clear, detailed views of the night sky. The filter is also effective at reducing the impact of moonlight, allowing you to observe faint deep-sky objects even when the Moon is visible.

The Optolong L-Pro filter is compatible with a wide range of telescopes and eyepieces, including refractors, catadioptrics, and reflector telescopes. It is also available in a variety of sizes to fit different types of optical tubes, including 1.25-inch and 2-inch versions. The filter is made of high-quality optical glass and is coated with a scratch-resistant layer to protect it from damage during use.

In summary, the Optolong L-Pro Light Pollution Reduction Filter is a must-have accessory for any serious astronomer looking to get the most out of their night sky observations. Its sophisticated optical design, wide range of light pollution blocking capabilities, and compatibility with a variety of telescopes make it an excellent choice for both beginner and advanced astronomers alike. Whether you're observing from a dark-sky site or a light-polluted urban area, the Optolong L-Pro filter will help you see the night sky in a whole new light.

1. Reduces light pollution: The Optolong Pro L-Pro filter is specifically designed to block out light pollution, allowing you to see fainter stars and deep-sky objects more clearly.

2. Enhances color accuracy: This filter helps to maintain the natural color balance of the night sky, allowing you to capture true-to-life color images.

3. Compatible with various telescopes: The Optolong Pro L-Pro filter is compatible with a wide range of telescopes, making it a versatile option for many astronomers.

4. Durable and easy to use: The filter is made of high-quality optical glass and is coated with a multi-layer anti-reflection coating, making it durable and easy to clean.

1. Cost: The Optolong Pro L-Pro filter is on the higher end of the price range for sky filters, which may be a barrier for some people.

2. Reduction of light intensity: While the filter reduces light pollution, it also reduces the overall intensity of the light that reaches your sensor. This can result in longer exposure times and potentially increased noise in your images.

If you're serious about astrophotography and want to capture the best possible images of deep-sky objects, the Optolong Pro L-Pro filter is a worthwhile investment. Its ability to reduce light pollution and enhance color accuracy can help you unlock the full potential of your telescope and imaging equipment. However, it's important to keep in mind the potential cost and reduced light intensity, and to ensure that it is compatible with your specific telescope.

If you're interested in purchasing the Optolong Pro L-Pro filter, I would recommend researching the specific telescope you own to make sure it is compatible. Additionally, consider the potential impact on exposure times and noise in your images and adjust your imaging strategy accordingly. Overall, the Optolong Pro L-Pro filter is a high-quality product that can help you take your astrophotography to the next level.

Details:

Back to top 2mm thick Scott b270 optical glass substrate material.

Being highly transparent to the main nebula emission lines at iii 496nm and 500nm, h-beta 486nm Ni 654nm 658nm h-alpha 656nm as well Sui 672nm unlike other light pollution filters such uh Cl's, l-pro is multi-band pass filter which offers better color balance by maximizing transmission band. Back to top 4.

Precision CBC-machined metal filter cell with sand blasted black anodized finish, anti-reflection treatment, and laser engraving. Works well on most emission nebulae, reflection nebulae and dark.

4nm, and the same holds true for visual star observations.

Suitable for color CDC cameras and unmodified desalts. Optical coating specifications multi layer anti-reflection coated.

High quality protective plastic storage case.

L-pro filter has a very low transmission reduction rate against continuous spectrum space objects, and thus is quite effective in suppressing light pollution sources when shooting galaxies, reflection nebulae globular star clusters.

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

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.

1nm, iii main uses and performance suitable for enhancing the contrast details both visual photographic purpose at urban suburban areas with heavy light pollution. Non-cementing optical substrate coating. These are not included in the item price or shipping cost.

Back to top 5.

This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil. Warning: Optolong filters are not designed for direct solar observation.

Other 2 astronomy filter with standard m48x0. Technical specifications both surfaces are fine optically polished, accurate to 1/4 wave length or better, and parallel within 30 seconds arc.

Precise and high blocking of major transmission lines artificial light pollution: Hg mercury at 435. 75 male filter thread no female thread, so it cannot be stacked with other filters.

The balanced transmission allows astronauts to be taken with minimal color cast in broadband emission objects such as galaxies, reflection nebulae and globular star clusters.

Na sodium at 598nm, 589.

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

Will combine the shipping weights and show you discounted cost.

L-pro is an excellent choice for light pollution suppression.

3nm, and Sui 672nm.

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