2011 年 12 月《天文学杂志》对 6mm 和 10mm Delos 的评论

摘自《天空与望远镜》 2011 年 6 月对 Delos 目镜的评论：

我们喜欢什么：

近乎完美的光学效果
“沉浸式”观察体验

我们不喜欢的地方：

我花了几个晚上用各种望远镜观察月亮、土星、星星和星云……

Delos 目镜“易于观察……。它们具有平坦的视野，从边缘到边缘都能看到绝对精确的星星，没有一丝色差。视野，特别是在白天，非常纯净，没有明显的色调。即使是最亮的星星，也没有一丝鬼影或反射”。

“然而，让我有点措手不及的是，最能描述这种感觉的，就是观察的体验。这显然是一种享受。”

“我感觉自己是从一个圆形窗口向外看，而不是通过目镜看出去。”

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.

Design

At the heart of the Founder Optics FOT016 is premium performance 3-element ED APO triplet refractor, designed by a famous optical designer in based in Japan. The optical performance is impressive as a two ED glass elements are employed.

Unlike most ED triplet telescopes which use only 1 ED glass element, Founder Optics adopted 2 ED glass of S-FPL 53 and S-FPL 51 to bring a remarkable image that you'll immediately spot with even a casual viewing. With two fluoro-crown ED glass elements and fully multi-coated optics, these Founder Optics refractors provide a crystal clear, superb sharp, zero aberration and distortion image to your eyes or camera sensor.

In addition, each element is fully separated or air spaced which is not common even among APO triplet telescopes. This offers further improvements to the already impressive optical quality.
