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.

2023 年 MARION ACT 杰出图书奖：儿童

评论：

“《 Swifty 》的插图由 Astred Hicks 绘制，非常精美。从新生鹦鹉蓬松的绒毛到它们在树叶上吃的虫子和树胶花的粘稠花蜜，她的插图中有很多值得学习的东西。书后面的信息页有助于解答《Swifty》中未解决的问题。CSIRO 出版网站上还有出色的教师笔记。我们最近评论了他们的几本书，每本书的质量都很高。强烈推荐。”
Susanne Gervay，CBCA 阅读时间，2022 年 9 月 25 日

“插画家 Astrid Hicks 也是一位获奖者，她为书页带来了色彩、欢乐和真情实感。她的插画既时髦又细致，Swifty 的彩虹羽毛在每一页上都闪闪发光。
这本书附有详细的教师注释，非常适合那些渴望了解澳大利亚野生动物的课堂。但它作为睡前故事同样精彩，无论有没有后面的额外注释……
超快鹦鹉 Swifty充满欢乐、启发和吸引力，绝对是赢家。”
Shaye Wardrop，儿童书评，2022 年 10 月 3 日

“ 《Swifty》是另一本精彩的书，它通过引人入胜的故事为年轻读者提供了了解澳大利亚极度濒危鸟类的机会。 Astrid Hicks 精美的扉页和光鲜亮丽的插图与正文相得益彰，让读者在每一页上都能探索到很多东西。”
Kathryn Beilby，ReadPlus，2022 年 10 月 3 日

“这是一部虚构的故事，充满了有趣的事实，适合 6 至 9 岁的儿童阅读。<...> 这本书涉及迁徙和如何处理受伤的鸟，以及导致斯威夫特鹦鹉濒临灭绝的因素——蜜袋鼯和猫的掠食以及栖息地的丧失。”
Sue Lashko，《堪培拉鸟类笔记》47(2)，2022 年

“我喜欢大声朗读这本书——书中有如此多精彩的形容词和描述性动词，向读者展示了斯威夫特鹦鹉如何在冬天带着宝宝从巢穴迁徙到北方，然后在春天和夏天回到南方的塔斯马尼亚繁殖。”
Vanessa RyanRendall，《我们可以！》（电子邮件通讯），2023 年 1 月 31 日

喜鹊为何会俯冲？我们为何对它们如此着迷？通过这本有趣的书，了解更多关于这些聪明、调皮又迷人的鸣禽的信息。

每个孩子的阅读水平都不一样，但我们建议 5 至 9 岁的儿童阅读这本书。

评论：

“这本书内容丰富，故事温馨！我很高兴我们能把这本精彩的书带到世界各地，来庆祝这些聪明、调皮、迷人的鸣禽，并让人们更多地了解它们。”
图画书读书俱乐部 (Instagram)，2022 年 8 月 16 日

“这本由妮可·戈德温 (Nicole Godwin) 创作的精彩图画书将成为年轻读者的最爱。苏珊娜·克里斯普 (Susannah Crispe) 创作的醒目封面和大胆插图将让读者感到愉悦，并与简单而迷人的文字完美搭配。”
Kathryn Beilby，ReadPlus，2022 年 9 月 1 日

“克里斯普的插图简直令人惊叹。色彩柔和美丽，细节丰富，场景只有一个（公园里的喜鹊树）。克里斯普创造了一个完整的世界，里面有多个角色，他们的故事都融入到他们的表情、衣服和配饰中。翻开每一页，认识一个新角色，想象他们是谁，是什么把他们带到公园，这真是一种享受。”
Shayne Wardrop，儿童书评，2022 年 9 月 2 日

“这本书结尾处附有说明性注释，并有全面的教学理念，涵盖科学、英语、伦理以及原住民和托雷斯海峡岛民的历史和文化。这是一本值得与每一位小学生分享的书，让他们明白喜鹊为什么会俯冲，它们就像人类父母一样，希望保护自己的孩子安全。”
底部货架，2022 年 9 月 4 日

“我喜欢 Godwin 简洁的文字，短小精悍的句子和重复使用‘swoop’这个词的模式。在 Crispe 生动的插图中，喜鹊大胆而自豪的形象以及生动的面部表情占据了中心位置，与公园游客的忙碌活动形成鲜明对比，背景是郁郁葱葱的澳大利亚公园的柔和灰色和绿色。<...> 我强烈推荐这本书给 6-9 岁的孩子，尤其是作为介绍鸟类或动物行为的教学资源。出版商的网站上有教学笔记。”
Barbara Swartz，CBCA 阅读时间，2022 年 9 月 19 日

“虽然只有大约 10% 的雄性喜鹊会真正发起攻击，但它们季节性的滑稽动作已成为澳大利亚民间传说的一部分。妮可·戈德温简洁、精心编写的文字为年轻读者提供了加入喜鹊“俯冲”的机会，而苏珊娜·克里斯佩的水彩插图完美地捕捉了厚脸皮的喜鹊爸爸的性格<...> 这是一种帮助年轻人欣赏这种壮丽鸟类的绝妙方式，它是我们城市环境的重要组成部分。”

Best of all, Celestron EclipSmart binoculars feature Solar Safe filter technology, ensuring ultimate protection from harmful solar radiation. Unlike detachable filters, which can be knocked off unexpectedly, EclipSmart Solar Binoculars feature built-in filters embedded in the objective lenses. Enjoy the Sun with confidence, knowing it’s impossible for the filters to become dislodged while you or your loved ones are observing.

Solar Safe Filter Technology

EclipSmart solar products feature Solar Safe filter technology—the ultimate protection from harmful solar radiation—including IR and UV light—plus 99.999% of visible light. Celestron Solar Safe filter technology is SAFE for direct observation of the Sun and has been independently tested to conform to and meet the transmission requirements of ISO 12312-2:2015(E), Filters for Direct Observation of the Sun.

Important safety note: inspect your binocular’s objective lens filters before every use. Do not use and discard if damaged, scratched, or separated from the frame in any way.

Crystal Clear View

With its multi-coated optics, the Celestron EclipSmart 10x42mm binoculars deliver high-contrast images of the Sun. These are white-light solar binoculars that provide a clear black-and-white image of the Sun. The Celestron EclipSmart 10x42mm Solar Binoculars also provide a generous field of view, so you can see the complete solar disk without moving the binocular.

The Body

A durable, rubber-armored aluminum housing protects your EclipSmart binocular from damage without weighing you down. The binoculars are comfortable to use for eyeglass wearers and non-eyeglass wearers alike, thanks to their durable folding eyecups. Fold them down for safe and effective use with your eyeglasses or keep them unfolded if you don’t wear glasses.

Accessories Included

Carry your EclipSmart binocular with the comfortable included strap. The binocular also includes a protective padded nylon case for storage and transport, and protective eyepiece and objective lens covers.

The Optolong L-Synergy filter is designed for astrophotographers using DSLR, color CMOS, or CCD cameras who want to achieve stunning narrowband results without switching to a monochrome system. By pairing traditional dual-narrowband (Ha & OIII) concepts with a unique “Ha & OIII + SII & OIII” approach, L-Synergy overcomes the usual limitations of colour cameras and makes Hubble-Palette–style imaging accessible to everyone.

With this filter, you can produce deep, high-contrast SHO-like images of emission nebulae using your existing colour camera—no additional SHO filters or monochrome upgrade required. It’s an affordable way to achieve professional-level results even under bright suburban skies.

Why Choose the L-Synergy Filter?

The L-Synergy is a dual 7 nm narrowband filter engineered for telescopes with an f/ratio of f/3.3 or slower. Years of optical refinement have produced a design that suppresses bright star halos while delivering extremely high transmission in the key emission bands.

• Selective Narrowband Performance
  Transmits only the OIII (500.7 nm) and SII (672.4 nm) nebula emission lines, rejecting unwanted wavelengths and light pollution.

• Exceptional Contrast and Signal-to-Noise
  By isolating the oxygen and sulfur signals, the filter produces a darker background sky and dramatically improves contrast—especially valuable in heavily light-polluted environments.

• Light-Pollution Resistant
  Filters out the vast majority of urban skyglow, allowing astrophotographers to capture clean, detailed nebula structure from almost any location.

Optical Design

L-Synergy is precision-engineered based on the spectral behaviour of emission nebulae and common light-pollution sources. Its carefully tuned passbands maintain consistently high transmission in both SII and OIII, ensuring accurate colour capture and high-quality data for processing.

The result: a powerful, easy-to-use narrowband solution that unlocks deep-sky imaging performance far beyond what typical colour cameras can achieve, giving more astrophotographers access to true SHO-style imaging.

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.

These Sky-Watcher Wide Field 2x54 Binoculars are an amazing way to experience the night sky. 

Sharp optics only magnify 2x, while offering large, 54mm, main lenses. This unique combination keeps your natural eyesight's wide field of view but allows you to see the night sky up almost two magnitudes fainter than what you can see normally. 

They have a 36 degree field of view, with an apparent field of field (AFOV) of a stunning 72 degrees. 

The unique binoculars will reveal:

• Countless stars, usually  hidden from your eyes
• Star clusters
• Milky Way star clouds
• Even galaxies!

Their lightweight construction makes them easy to hold even for extended observing sessions. The compact carry bag is included.

The M54-M48-2 adapter is mainly used for connecting to the 2”EFW and M54 filter drawer.

The thickness of this adapter is 2mm.
