Farpoint 激光准直器 635nm（2-1.25 英寸）

所有 Farpoint 激光准直器均享有终身校准保证。我们将免费重新校准任何 Farpoint 激光准直器！但 Farpoint 激光器保持出厂校准。这是因为我们拥有坚固的激光器主体和（最重要的是）我们独特的校准螺钉设计（如下所述）。

Farpoint 激光器有八个对准螺钉，而不是像其他激光器那样有六个、四个甚至三个。激光二极管的两端由两组直接相对的螺钉固定，而不是交错排列（顶部孔、底部孔、顶部孔），这样二极管可以移动，从而实现精确和持久的对准。同样，只有 Farpoint 激光器具有这种优越的对准螺钉排列，其中四个直接相对的螺钉对准激光二极管的顶部，另外四个直接相对的螺钉对准激光二极管的底部。

Farpoint 激光体由一整块铝通过一步加工精密加工而成，可实现完美对准。

Farpoint 激光器的孔径较小（0.76 毫米或 30/1000 英寸），可减少斑点并更精确地读取激光束在望远镜镜面上的位置。Farpoint 是业余天文学市场上所有激光器中孔径最小的。

A guide to the special birds found across Australia’s vastly varied landscapes.

From the eastern rainforests to the central deserts, Australia is home to some 900 species of birds. Finding Australian Birds covers over 400 birdwatching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and Uluru in the Red Centre of the Northern Territory, the Great Barrier Reef in Queensland, an amazing diversity of forests along the eastern Australian seaboard, including some of the world’s tallest forests in Tasmania, the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee woodlands and remote Kimberley region in Western Australia.

Chapters are arranged by state or territory and begin with an overview. Birdwatching sites are then grouped by region to provide specific details on target species, access and useful information such as accommodation and facilities. This second edition includes over 30 new birdwatching sites and updated information on site access. The book also provides a comprehensive ‘Bird Finding Guide’, listing all of Australia’s birds with details on their abundance and where exactly to see them.

Finding Australian Birds will be valuable to both Australian birdwatchers and international visitors. It will assist novices, birders of intermediate skill and keen ‘twitchers’ to find any Australian species.

Praise for the first edition:

"Twitchers will find this a most agreeable companion but all bird-loving travellers should pop a copy in their backpack, along with good binoculars."
Susan Kurosawa, Weekend Australian, June 2014

"The amount of detailed information within its pages will be enough to make even the best-travelled birders eager to get out and check a few more sites"
Chris Watson, Australian Birdlife, June 2014

"This excellent birdwatching site guide by Tim Dolby and Rohan Clarke will save you time if you are planning an Australian birdwatching trip, and is sure to help you find more of your target species... you wouldn’t want to plan an Australian birding trip without consulting this one."
Michael Szabo, Birds New Zealand (16), December 2017

Includes:

• Fully updated second edition, featuring new sites and current site access details.
• Up-to-date information on 400+ good birding locations in Australia, written by experts with first-hand knowledge of the sites.
• An easy-to-use travel companion for local and international birdwatchers on Australia’s best natural sites.

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. 

Quality

In order to complete this unique design, it requires a very high level machining and assembly capability. Founder Optics partner with an experienced factory located in Taiwan with over 50 years experience in precision manufacturing, especially for Japanese companies. 

Besides manufacturing know-how, the high standard of quality control is also crucial to producing FOT86 and FOT106 telescopes. This is recorded in a Quality Certification Card.

Every unit is thoroughly tested, and these unique records help customers understand the quality of their telescope. Founder Optics take their quality checking very seriously as they aim to offer the best triplet APO telescopes to BINTEL customers. 

Focuser - 2.7'' Rack & Pinion

Perfect Hybrid Drive system with 8 Ball bearings- More Smoothly!

2sets of 4pcs ball bearing at 2 sides between the drawtube and the focuser handle linear travel of the focuser. Once the locked the knob, there is no gap among the drawtube, 8pcs ball bearings, and the focuser cover. It does not only keep the focuser always paralleled the optic axis, but also keep it moved very smoothly.
