Review BAADER PLANETARIUM Premium Eyepiece Filter Yellow 495nm Longpass

The Baader Planetarium FCFY-2 Eyepiece Filter 495nm Longpass (Item No: 2458311) is a high-quality optical filter designed for astrophotography and visual observation. This filter is specifically engineered to block wavelengths below 495nm, allowing only longer wavelengths to pass through. This feature makes it ideal for enhancing the contrast and detail of objects in the deep sky, such as nebulae and planets, by reducing the brightness of stars and other short-wavelength light sources.

The FCFY-2 is made of Schott B270 glass, which is known for its excellent optical quality and durability. The filter has a thread diameter of 2" and is 1.1mm thick, making it compatible with most 2" eyepieces. It also features a multi-coated surface, which reduces reflection and increases light transmission.

The Baader Planetarium FCFY-2 Longpass Filter is a valuable tool for astrophotographers and visual observers who want to bring out the finest details in deep-sky objects. Its ability to block unwanted light and enhance contrast can help you capture stunning images or simply enjoy a more immersive viewing experience. Whether you're a seasoned astronomer or a newcomer to the hobby, this filter is a worthy addition to your astronomy equipment.

1. Enhances Contrast: The longpass filter blocks out shorter wavelengths of light, allowing more red and near-infrared light to pass through. This can enhance contrast and detail in deep sky objects, making them easier to observe.

2. Ideal for Planetary Observation: The 495nm filter is specifically designed for planetary observation, blocking out the light pollution and solar glare that can make planets harder to see.

3. High Quality: Baader Planetarium is known for producing high-quality optical filters, and the FCFY-2 is no exception. It is made of optical glass and coated with a multi-layer anti-reflection coating.

4. Durable Construction: The filter is made of sturdy aluminum and has a secure threaded mount, ensuring it will last for many observations to come.

1. Expensive: Compared to other filters on the market, the Baader Planetarium FCFY-2 is quite expensive.

2. Limited Use: The filter is specifically designed for planetary observation and may not be as useful for other types of astronomy, such as deep sky or solar observation.

3. Requires Additional Purchase: The filter requires a specific adapter to fit onto your eyepiece, which is not included in the purchase price.

The Baader Planetarium 2458311 FCFY-2 495nm Longpass Eyepiece Filter is a high-quality filter that can enhance contrast and detail in planetary observation. However, its high price and limited use may make it a less suitable option for beginners or those on a budget. If you are a serious planetary observer and are looking for a top-of-the-line filter, then this may be a worthwhile investment. However, for other types of astronomy, there may be more cost-effective options available.

If you are a serious planetary observer and have the budget for it, the Baader Planetarium 2458311 FCFY-2 495nm Longpass Eyepiece Filter is a high-quality option that can enhance your observing experience. However, if you are a beginner or have a limited budget, there may be other filters on the market that offer similar performance at a lower price point. It's important to do your research and consider your specific needs before making a purchase.

Details:

Only one filter is needed for benefiting.

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

Striae-free substrates are polished parallel to 30 seconds of avoid wedge errors. No reduction in sharpness, even at high magnifications or when using the filter far ahead of focal plane ie, digital imaging, front a diagonal bonfire.

Only Baader colored filters have the optical quality necessary for use this far ahead of focal plane. 25 residual reflections Baader filters are unique, no other colored filter incorporates anti-reflection multi coatings.

Extremely high transmissions result in maximum contrast and isolation of planetary details, even with smaller telescopes.

Not just another colored filter.

This maximizes the transmission and minimizes reflections. Will combine the shipping weights and show you discounted cost.

The coatings are also different for each of filters, in order to match coating performance filter curve color.

Baader Planetariums premium colored filters bring a new level of quality and performance to planetary contrast enhancement.

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