Review EXPLORE SCIENTIFIC F/6.5 Air Spaced Triplet Apo And Extras

The Scientific ED140 Air Spaced Triplet APO FPL53 Extra-Low Dispersion Objective Lens is a high-performance, versatile instrument designed for advanced astronomical observation and imaging. This lens is part of a select group of apochromatic lenses, which are renowned for their ability to correct for chromatic aberration, ensuring sharp, true-color images even at high magnifications.

The ED140 in this lens's designation refers to the Extra-Low Dispersion glasses used in its construction. These glasses have a low refractive index and a high anomalous dispersion, which means they can correct for both chromatic and spherical aberration. This results in images that are not only free of color fringing but also with high contrast and resolution.

The 140mm aperture of this lens allows for a significant amount of light to enter the optical system, making it an excellent choice for low-light observation and imaging. The air spaced triplet design further enhances its light-gathering capabilities and reduces the risk of internal reflections, leading to improved image quality.

The APO (Apochromatic) designation indicates that this lens uses three elements of different materials with varying refractive indices to correct for chromatic aberration. This results in images that are not only free of color fringing but also with high contrast and resolution.

The FPL53 glass used in the lens's construction is a high-quality, fluorite-based material that is known for its exceptional clarity and color correction abilities. This makes it an ideal choice for high-end, professional-grade telescopes and other optical instruments.

In summary, the Scientific ED140 Air Spaced Triplet APO FPL53 Extra-Low Dispersion Objective Lens is a high-performance, versatile instrument that is perfect for advanced astronomical observation and imaging. Its Extra-Low Dispersion glasses, air spaced triplet design, and use of FPL53 glass ensure sharp, true-color images with high contrast and resolution, even in low-light conditions. This lens is a must-have for any serious astronomer or imaging enthusiast.

1. Exceptional Optical Performance: This telescope features an apochromatic triplet lens system, which is designed to minimize chromatic aberrations, resulting in sharp and color-accurate images.

2. High Light Gathering Capability: The FPL53 lens material has a high refractive index, allowing the telescope to gather more light, resulting in brighter and more detailed images, especially in low light conditions.

3. Wide Field of View: The air-spaced triplet design provides a wide field of view, allowing you to observe a larger area of the sky at once.

4. High Resolution: The high-quality optics of this telescope allow for high-resolution images, making it perfect for astrophotography or detailed observations of celestial objects.

1. High Cost: This telescope is one of the more expensive options on the market, making it a significant investment for many hobbyists.

2. Large Size and Weight: Due to its large aperture and high-quality optics, the telescope is quite large and heavy, which may make it difficult to transport or set up in some locations.

3. Requires a Sturdy Mount: To take full advantage of its high-resolution capabilities, the telescope requires a sturdy and heavy-duty mount to minimize vibrations and maintain a steady image.

The FPL53 Scientific ED140 Air-Spaced Triplet Apo is an exceptional telescope for serious astronomers and astrophotographers who require the highest level of optical performance. Its wide field of view, high light gathering capability, and high resolution make it a great choice for observing a variety of celestial objects. However, its high cost, large size, and weight may make it a less practical option for casual hobbyists or those with limited budgets or space.

If you are a serious astronomer or astrophotographer with a significant budget and the space to accommodate a large telescope, the FPL53 Scientific ED140 Air-Spaced Triplet Apo is an excellent investment. Its exceptional optical performance will allow you to make the most of your observing and imaging sessions. However, if you are a casual hobbyist or have a limited budget, there are other more affordable and portable options available that may better meet your needs.

Details:

Condition is excellent. I am selling my Explore Scientific ED140 Air Spaced Triplet APO with FPL53 premium low dispersion glass. Thus the Price. Please study the pics, as scope is in excellent condition.

This is a 6k telescope, and it in excellent condition. Pals see the reviews and do web search to exact specs. It comes with the Mfr Hard Case, finder and Illuminati, 0.7 FF/Focal Reducer which currently sells for 479. Has the 3 Hex Focused.

No major dings or scratches to the carbon fiber, and lens is in excellent condition with just a few specs of dust. Start test is excellent.
