Sky-Watcher Esprit 100 ED APO Refractor

Sky-Watcher Esprit 100 ED APO Refractor: Unleash the Universe

The Sky-Watcher Esprit 100 ED APO Refractor is a premium telescope designed for both amateur and professional astronomers who demand the highest quality optics and performance. This telescope is a part of Sky-Watcher’s renowned Esprit series, known for its exceptional build quality, advanced optical design, and comprehensive accessory package. Whether you are a visual observer or an astrophotographer, the Esprit 100 ED APO Refractor offers a versatile and powerful tool to explore the night sky.

Advanced Optical Design

At the heart of the Esprit 100 ED APO Refractor is a 100mm air-spaced triplet apochromatic lens system. This advanced optical design incorporates FPL-53 extra-low dispersion (ED) glass and Schott BK-7 glass, which work together to virtually eliminate chromatic aberration and deliver stunningly sharp and high-contrast images. The triplet configuration ensures that all three primary colors (red, green, and blue) come to the same focal point, resulting in true-to-life color reproduction and pinpoint star images.

The optics are fully multi-coated with Sky-Watcher’s proprietary high transmission coatings, which maximize light throughput and minimize reflections. This ensures that you get the brightest and most detailed views possible, whether you are observing planets, deep-sky objects, or the Moon.

Precision Field Flattener

One of the standout features of the Esprit 100 ED APO Refractor is its included thread-on doublet field flattener. This accessory is essential for astrophotographers, as it corrects for field curvature and provides a flat imaging plane across the entire field of view. This means that stars at the edge of your images will be just as sharp as those in the center, allowing you to capture breathtaking wide-field astrophotography with pinpoint stars from edge to edge.

Robust Build Quality

The Esprit 100 ED APO Refractor is built to last, with a rugged and durable construction that can withstand the rigors of regular use and transportation. The telescope features a heavy-duty 2.7-inch dual-speed focuser, which provides smooth and precise focusing control. The focuser is designed to handle heavy imaging equipment without any slippage, ensuring that your camera stays securely in place during long exposure astrophotography sessions.

The telescope also includes a retractable dew shield, which helps to prevent dew formation on the lens and protects the optics from dust and debris. The dew shield can be easily extended or retracted as needed, making it convenient for both storage and use in the field.

Comprehensive Accessory Package

Sky-Watcher has thoughtfully included a range of high-quality accessories with the Esprit 100 ED APO Refractor, making it a complete package that is ready to use right out of the box. The telescope comes with an aluminum hard case for safe storage and transport, ensuring that your investment is well-protected when not in use.

An 8×50 right-angle finderscope is included to help you locate and center celestial objects with ease. The finderscope features a comfortable right-angle design, which makes it easier to use when the telescope is pointed at high angles.

For visual observers, the Esprit 100 ED APO Refractor includes a 2-inch dielectric diagonal, which provides bright and high-contrast views with minimal light loss. The diagonal is equipped with a compression ring to securely hold your eyepieces without marring their barrels.

Astrophotographers will appreciate the included M48 camera adapter, which allows you to easily attach your DSLR or dedicated astronomy camera to the telescope. This adapter ensures a secure and stable connection, so you can focus on capturing stunning images of the night sky.

Versatility and Performance

The Sky-Watcher Esprit 100 ED APO Refractor is a versatile telescope that excels in both visual observation and astrophotography. Its compact and portable design makes it easy to transport to dark sky sites, while its robust construction ensures that it can handle the demands of regular use.

For visual observers, the Esprit 100 ED APO Refractor offers breathtaking views of the Moon, planets, and deep-sky objects. The high-quality optics provide sharp and detailed images, allowing you to see fine details on the lunar surface, the rings of Saturn, the cloud bands of Jupiter, and the intricate structures of nebulae and galaxies.

Astrophotographers will find the Esprit 100 ED APO Refractor to be an exceptional imaging instrument. The combination of the triplet apochromatic lens system and the included field flattener ensures that your images are sharp and free of aberrations across the entire field of view. Whether you are capturing wide-field images of the Milky Way or detailed shots of individual deep-sky objects, the Esprit 100 ED APO Refractor delivers outstanding performance.
