saxon Plossl eyepieces can be used on all types of telescopes - refractors, reflector, and catadioptrics such as Celestron SCT telescopes.

Featuring a 4-element design, this Plossl eyepiece ensures maximum light transition, minimises spherical aberration, distortion, astigmatism, and off-axis colour. The edge-to-edge blackened optics provide excellent contrast across the 52° apparent field of view.

This 32mm size will offer a lower magnification than the 25mm size provided as standard with most telescopes. It's a handy way to obtain a wider field of view for large deep-sky objects including many nebulae and star clusters.

The oversized optical elements provide long eye relief while stray light is eliminated by the fold back rubber eyecups.

Ever tried look at the Full Moon through a telescope? You'll know just how bright it can be!

The saxon 1.25" Moon Filter helps reduce glare and increase the contrast of the Moon allowing you to see the fine details on craters, mountains and across the Lunar plains, called Mare.

The James Webb Space Telescope took three decades from conception to launch but the wait has been worth it. The results of the most anticipated telescope of the 21st century have been nothing short of spectacular.

The idea for the James Webb Space Telescope (JWST) was first raised in 1989, well before the enormously successful Hubble Space Telescope was launched. The infrared telescope with a mirror larger than four meters was launched on Christmas Day 2021.

In the summer of 2022, NASA released the first scientific images from Webb to the amazement of more than 300,000 viewers who watched the event live, and hundreds of millions around the world who have viewed Webb's images since then.

Webb's Cosmos is written in the spirit of Terry Dickinson's enormously popular book Hubble's Universe, which has sold over 100,000 copies. This book contains both the classic Webb images that have already become famous and the latest images from the frontiers of science taken by Webb, some of which appear here for the first time.

Author Marcin Sawicki is a professional astronomer who is an active user of Webb's images and data. He brings a wealth of knowledge and personal experience to the book and explains the science behind the images in accurate but accessible and engaging language.

Webb's Cosmos first provides the needed historical and scientific background to understand how the telescope works and what it can do. The book then presents a curated selection of some 200 photographs with descriptive captions that narrate these images of the distant universe. Chapters include:

• Stars and gas clouds
• Galaxies both near and far
• Planets and our solar system
• Exoplanets.

AUTHOR:
Marcin Sawicki is a professional research astronomer who has been involved with the James Webb Space Telescope Project for more than two decades and is now extensively using Webb for research. He is the co-author of 20 research papers based on data taken with Webb. A professional educator and experienced science communicator, Sawicki is Professor of Astronomy and Physics at Saint Mary's University and has held prestigious appointments: Canada Research Chair, Canadian Space Agency Science Fellow and Plaskett Fellow.

The Saxon 50mm MK II Guidescope is a compact and lightweight guidescope designed for astrophotography. With a 50mm aperture and a high-quality optical design, it provides precise guiding for long-exposure imaging. The guidescope is easy to mount and compatible with most telescope setups, ensuring accurate tracking and sharp images.

提供非常宽的视野，具有精确的视场边缘清晰度。这些最新进展提供了完全多镀膜的光学设计，并采用高级异国情调的光学玻璃，以实现最佳的图像色彩和亮度校正。黑色镜片边缘提供增强的对比度并有助于减少反射，而共焦设计在目镜之间切换时几乎不会产生焦点变化。凭借宽大的眼部缓解，享受舒适的观察体验。与传统 Plössls 相比，UHD 目镜在色差和边缘失真校正方面提高了 40%。

采用防水设计，UHD 目镜可抵御雾气和户外大气元素。边缘呈黑色且为共焦。以全新、更佳的视角观察您喜爱的天体。

Born and raised in remote Broken Hill, Trevor Barry left school after year ten to work in the mines. Years later, a single glimpse of Saturn through a colleague's telescope knocked Trevor's world completely off its axis, turning his whole life upside down.

With his newfound passion and armed with decades of outback know-how, Trevor set about building an observatory in his backyard using bits and pieces from his shed, a second-hand washing machine motor, rainwater tank parts and an old catamaran wire. It took some canny negotiations with his wife, Cheryl, 'the Gorgeous and Adorable', whose prized garden took a battering - especially when he decided to add a second storey - but before long Trevor was not just gazing at the stars but capturing extraordinary images of the planets.

Over the years, Trevor's love affair with Saturn, 'the ringed jewel of the solar system', only grew more passionate, and in his early fifties he did a degree in astronomy, topping his class.

When he recorded a massive storm on Saturn from his backyard observatory, he alerted NASA. The world's greatest space agency took note and invited Trevor to contribute to its interplanetary research - leading to opportunities far beyond Broken Hill and even Trevor's wildest dreams.

Today, when he's not tending the greens at his local bowls club, Trevor can usually be found in his backyard, collecting data for international research projects. His work is held in high regard by professional astronomers, and his observations are published in peer-reviewed scientific journals around the world.

About Trevor

Trevor Barry has called Broken Hill home his whole life. At 17, he started work in the local mines and built a good life there, married to his high school sweetheart, Cheryl, the Gorgeous and Adorable. But then Trevor fell in love again - not with Cheryl, but with a planet: Saturn. Just one look through a telescope changed his life forever. First he built his own telescope, and then an observatory - until finally, at 51, Trevor decided to gaze at the stars full time and enrolled at university to study astronomy. He now collects data vital to NASA research and is renowned for his extraordinary photographs of the planets.

Featuring a 4-element design, this Plossl eyepiece ensures maximum light transition, minimises spherical aberration, distortion, astigmatism, and off-axis colour. The edge-to-edge blackened optics provide excellent contrast across the 52° apparent field of view.

This 6.3mm size offers higher magnification than the 10mm eyepiece that comes as standard with many telescopes. Ideal for planets especially Saturn, Jupiter and Mars.

The new SV II range benefits from the same great optics in the original SV binoculars and continue to offer an excellent price/performance ratio with multi-coated lenses, lightweight body, and sleek ergonomics that made the original line-up so popular. A tough, polycarbonate, fully waterproof, and nitrogen filled body makes these binoculars perfect for the great outdoors, whatever the weather.

Phase-Coated Roof Prism

The Schmidt prism roof surface is phase corrected to ensure sharp images for the most outstanding image contrast.

All-Surface Multi-Coating

The all-surface multi-coated optical system provides a precise color definition for a brighter and sharper image.

Waterproof and Fogproof

The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure image clarity.

Twist-Up Eyecups

Twist-up multi-step eyecups allow customization for easy viewing even when wearing eyeglasses.

What's Included

The Kowa SV Series binoculars come with a durable case with a belt loop, a premium neoprene neck strap, a high-quality rainguard, and objective lens covers for comprehensive protection.
