L-Quad Enhance Filter (L-QEF) is a quad bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths, especially light pollution generated by artificial lighting (including mercury and sodium lamps), as well as the effects of natural skylight-induced effects on the shot, thus effectively enhancing the contrast and details of the celestial bodies, and making the objects more distinct and stereoscopic. This filter provides better color balance while improving resistance of light pollution. L-QEF can be used for both wide field astrophotography, such as the Milky Way in Summer and Winter, and deep sky objects such as nebulae, galaxies, star clusters, and so forth; It allows you to save a lot of time during the shooting process and get better results at the same time. The design of quad bandpass maximises the colour balance of nebulae, galaxies and other broadband spectral targets.

Key Features:

• Cuts out light pollution from mercury and sodium lamps and produces a nice broadband image with minimal colour cast;
• Signal-to-noise ratio (SNR);
• Near IR cut-off to 1000nm, reducing the effects of IR noise;
• L-QEF has more than 90% transmittance of the nebula emission lines at H-Beta/OIII/H-Alpha/SII, with cut-off depth from OD2 to OD4, thus providing a significant increase in resistance to light pollution. L-QEF is good for night sky from Bortel 1 to Bortel 7 levels; (Bortel 8, Bortel 9 environments shall not be recommended, kindly chose Optolong other narrow-band filters, 3nm, 7nm type of filters are available.);
• Suitable for wide range of deep sky targets: it covers most nebulae, galaxies, star clusters, reflected and emitted line signals astronomical objects with higher contrast and rich details while maintaining excellent colour balance. L-QEF is superior to other filters of the same type.

Spectrum and Characteristic

Based on the characteristics of celestial bodies’ emission lines and light pollution emission lines, L-Quad Enhance filter effectively reduces the impact of light pollution and suppresses the background light of astronomical objects, thus effectively enhancing the contrast and details of the celestial bodies. Using L-QEF filter can help you save a lot of time during the shooting process, yet obtaining incredible results.

Antlia SII 3nm Pro narrowband filter optimizes the FWHM (full-width half maximum) to 3nm bandpass. As the bandwidth becomes narrower, the 3nm Pro narrowband filters enhance the contrast of emission targets by lowering the unwanted background signal. Antlia SII 3nm Pro filter is designed to deliver 88% transmission at the 671.6nm line which provides you with the maximum signal and well-defined nebulae structures.

Conventional broader narrowband filters cause a heavy loss in transmission due to the strong (Center Wavelength (CWL)-shift. We guarantee T>88% within 1nm range of the center bandwidth, which means that the 3nm Pro narrowband filter can guarantee high transmittance for working with both long focal ratios and fast optical systems. Blue-shift data show that Antlia SII 3nm Pro filters can be used with nearly all systems as fast as f/3 with minimal loss in emission signal and meet the requirements of fast optics like Hyperstar and RASA.

The out-of-band blocking specification is rated OD5 (0.001%) which delivers an excellent SNR(signal-to-noise ratio) and effective cut-off rate to minimize interference from other wavelengths. Improved sharp cut-off astrophotography 3nm Pro filters are designed to minimize halos around bright stars.

Application and Performance:

High transmittance and smallest bandwidth to maximize contrast

A steep spectral profile minimizes halos around bright stars

A single substrate to eliminate internal reflections

Narrowband Objects: SII Emission Nebulae, Planetary, Wolf-Rayet Nebulae and Supernova Remnants

Use in light-polluted areas and dark sites

Annals of the Deep Sky Vol 10 explores the constellations of Draco, Equuleus, Eridanus and Fornax, each with a bounty of fascinating stars and nonstellar objects. Draco contains numerous double stars, such as the wide pair Nu Draconis, two fifth-magnitude stars that look alike but are nonetheless very different. One of Draco’s most popular deep-sky objects is the Cat’s Eye Nebula (NGC 6543), the first planetary nebula to be decoded spectroscopically, by William Huggins in 1910. Modest Equuleus can at least boast the spiral galaxy NGC 7040, discovered by Mark Walrod Harrington in 1882. We include a brief, but strange, backstory of Harrington. Eridanus, too, may be a small constellation but it contains the intriguing galactic group associated with NGC 1723 and a “lopsided” galaxy, NGC 1637. Fornax is replete with interesting galaxies, including NGC 1097 with its peculiar nucleus, the shell system NGC 1344, and the “three-ringed” galaxy NGC 1326. And don’t neglect S Fornacis, an odd sun that occasionally exhibits superflares.

Annals of the Deep Sky is a comprehensive reference that guides amateur and semipro astronomers into every mind-boggling corner of the observational universe. Each volume presents extensive descriptions of prominent stars and deep-sky objects. No other popular work in astronomy provides the comprehensive historical background and astrophysical appraisals of prominent stars and celestial objects.

DO NOT LOOK AT THE SUN WITH ANTLIA FILTERS.

When we design filters for astronomy imaging systems, we look at how they will work together with optical systems, carefully designing the blocking and bandpass parameters to achieve an optimum result. The out-of-band blocking rate is a very important performance index since it is designed to sharply attenuate off-band wavelengths. The result is that the Antlia OIII 3nm Pro filter delivers excellent contrast with extremely dark backgrounds whilst delivering a high transmission of the OIII signal. Such filters are more difficult to produce to a consistently high standard.

Each filter is individually tested and scanned to ensure that the quality meets the high-performance parameters. The end result is a filter that achieves excellent contrast but with a higher production cost. We believe the price-to-performance ratio compares more favorably than similar premium filters in the market.

Whether you're a bird watcher, sports fan or just like being out enjoying nature the Vixen ATREA II H14x42WP Binoculars serve up sharp, clear, AND stable views without the shakiness that often comes with higher power binoculars.

Built-in image stabilization

Binoculars are handy to travel with and an ideal way to look at the world around us. One problem is that as you increase the magnification to bring things closer to you, any vibrations or hand shakes and movements are also magnified. This means you'll have to concentrate on holding your binoculars steady rather than just enjoying the view.

The Vixen ATREA II H14x42WP Binoculars solve the problem with image shakes with a 2-axis gimbal control image stabilization mechanism. This enables them to effectively compensate image shifts of +/- 3 degrees at vibration correction angle (with all directions) and offers a stable field of view of the binoculars. Even micro-vibrations are controlled successfully, and you will be able to enjoy observing a glow in a bird’s eyes and a look of bird feathers in detail.

Great for Astronomy too!

At night you'll be able to spot fainter stars and astro objects that are hard to see in ordinary binoculars due to the image stabilization feature.

Two image-stabilization modes - moving objects and distance viewing

The binoculars come equipped with two anti-vibration modes that can be selected to suit your needs:

• V1 Mode: Absorbs small vibrations and jitters. (This mode is preferable to use when you want to look at a moving object.)
• V2 Mode: Absorbs large vibrations moved slowly. (This mode is preferable to use when you want to appreciate a stationary object.)

Multi-coated optics throughout

Each of the lens surfaces is coated with multilayers of anti-reflection coatings. The prisms are phase coated to reduce halation and enhance resolution. In addition, high reflection coatings are applied. These three types of optical coatings eliminate stray light and loss of light thoroughly to achieve an extremely bright and clear field of view.

12 Hour battery life with standard AAA batteries

Two AAA batteries are used for the power source. AAA batteries are available at any Coles, Woolies, 7-11 stores or servos everywhere. This means you can travel with the ATERA II H14x42WP to a local event or take them with you on a trip across the country knowing you'll always be able to find fresh batteries.

Waterproof

The ATERA II H14x42WP binoculars have IPX4 waterproof rating and this means they can be used in a wet environment with no worries about moisture causing damage.

This book reinvigorates my love of birds and birding and makes clear how lucky we are to have such amazing riches. And that is some powerful art."
Kate-Gorringe-Smith, Australian Birdlife, June 2017

"Not only does The Australian Bird Guide successfully provide a rich, contemporary bird identification book, it has the potential to play a far more significant cultural role – in cataloguing the full extent of the glorious variety of Australian birds it becomes a palpable celebration of the wonder of nature."
Sean Dooley, Sydney Morning Herald online, 28/7/17

"If you are looking at getting a field guide to the birds of Australia, the ABG is undoubtably the best."
Michael Szabo, Birds New Zealand (14), June 2017

"Compared with all other Australian bird guides, the text and most of the illustrations are on a higher level... The cornucopia of high quality illustrations – including numerous smaller sketch-ups illustrating such things as foraging behaviours, honeyeater corroborees, and size comparisons with similar possible species – puts the guide in the upper echelon of bird guides globally... For me, this volume by Menkhorst and colleagues has become my new favourite."
Eliot Miller, Emu - Austral Ornithology 117(3), July 2017

"Birds are illustrated in poses that best highlight diagnostic features. Seabirds are depicted almost exclusively in flight, precisely as most will encounter them at sea. The text is detailed without being too over-the-top, featuring all of the expected information and including helpful notes on recent taxonomic changes, distributional information that might be too granular to identify on the maps, and behavioural notes which might assist finding the bird and separating it from confusing species. The maps are clear and show all subspecies."
Chris Watson, Australian Birdlife, June 2017

"the ABG is undeniably the most comprehensive field guide to be published in Australia to date, surpassing previous guides in the quantity and accuracy of illustrations and pertinent information."
Richard Noske, Australian Book Review, October 2017

Product Information TE-9Z 20-60X ZOOM EYEPIECE

Kowa's TE-9Z 20-60x Zoom Spotting Scope Eyepiece is compatible with TSN-82SV, TSN-660, and TSN-600 series spotting scopes to provide a wide magnification range that will satisfy most of your observational needs. Using a simple bayonet mount, it installs easily, and the knurled dial makes changing the zoom quick and sure. The TE-9Z features a wide apparent field of view – 42-126° with 60mm and 66mm scopes and 40-126° with the 82mm scope – and a 16/16.5mm eye relief value for comfortable glassing, even with eyewear.

For each species, the authors examine the many-and-varied common names and full scientific name, with derivation, translation and a guide to pronunciation. Stories behind the name are included, as well as relevant aspects of biology, conservation and history. Original descriptions, translated by the authors, have been sourced for many species.

As well as being a book about names, this is a book about the history of the ever-developing understanding of birds, about the people who contributed to this understanding and, most of all, about the birds themselves. This second edition has been revised to follow current taxonomy and understanding of the relationships between families, genera and species. It contains new taxa, updated text and new vagrants and will be interesting reading for anyone with a love of birds, words or the history of Australian biology and bird-watching.

Reviews:

"The wealth of meticulously researched information presented in this book makes it an essential reference for anyone keen about birds and words, and a very welcome addition to ornithological literature."
Virgil Hubregtse, The Victorian Naturalist 136(6), 2019

"This wonderful book by Ian Fraser and Jeannie Gray fills a niche in the available bird literature as it seeks, and achieves admirably, to explain in depth how the Latin and English names of our Australian birds came about. ...If you are wondering what a Dick, Dick, the Devil is, or a howling jackass, or even a doubtful reed-bellower, then this is the book for you."
Libby McGill, Western Australian Bird Notes 172, December 2019

"In truth there is little for the carping critic to cavil about. All in all, Australian Bird Names: Origins and Meanings is a most valuable reference work, rich in interesting information of a kind not easily found elsewhere. It is good to see that CSIRO Publishing appreciates the need to keep it up to date."
Kevin Windle, Canberra Bird Notes 44(3), December 2019

Swifty grows from a hatchling to a fledgling in the blue-gum forests of Tasmania. She is then ready to make a challenging migration, following the blossom trail across Bass Strait to mainland south-eastern Australia.

Swifty faces many threats and dangers, but she must return home. Will she make it?

Fly with Swifty in this beautifully illustrated story and learn how to spot a swift parrot and help protect them.

Reading level varies from child to child, but we recommend this book for ages 6 to 9.

Highly Commended, The MARION ACT Notable Book Awards 2023: Children's

Reviews:

"Swifty is beautifully illustrated by Astred Hicks. There is so much to learn in her illustrations from the fluffy down of newborn parrots to their feasting on lerps on leaves and sticky nectar from gum blossoms. The information pages at the back of the book, help to unlock the open questions in Swifty. There are also excellent teacher notes at the CSIRO publishing website. We have reviewed several of their books lately and the quality is high with all of them. Highly recommended."
Susanne Gervay, CBCA Reading Time, 25 September 2022

"Illustrator Astrid Hicks, also an award-winner, brings colour, joy and so much heart to the pages. Her illustrations are funky and detailed, and Swifty’s rainbow plumage shines bright one very page.
With detailed teachers notes to accompany it, this book is great for classrooms keen to learn about Australian wildlife. But it’s equally brilliant as a bedtime story, with or without the extra notes at the back...
Joyful, inspiring and engaging, Swifty the Super-fast Parrot is a winner."
Shaye Wardrop, Kids' Book Review, 3 October 2022

"Swifty is another wonderful book that provides younger readers with the opportunity to learn about one of Australia’s critically endangered birds through an engaging story. The stunning endpapers and glossy illustrations by Astrid Hicks perfectly complement the text and offer the reader so much to explore on each page."
Kathryn Beilby, ReadPlus, 3 October 2022

"This is a fictional tale full of interesting facts aimed at 6- to 9-year-olds. <...> This book touches on migration and what to do with an injured bird, as well as the factors contributing to the Swift Parrot being critically endangered - predation, by sugar gliders and cats, and habitat loss."
Sue Lashko, Canberra Bird Notes 47(2), 2022

"I loved reading this book out loud - so many wonderful adjectives and descriptive verbs to show the reader how the Swift Parrot moves about from a nest hollow with her babies to a migration north during Winter and then back down south to Tasmania to breed during spring and summer."
Vanessa RyanRendall, We Can! (email newsletter), 31 January 2023

Why do magpies swoop and why do we have such a fascination with them? Discover more about these clever, cheeky and charming songbirds through this delightful book.

Reading level varies from child to child, but we recommend this book for ages 5 to 9.

Reviews:

"An informative delight with a heartwarming story! I love that we have this wonderful book out in the world to celebrate and create more understanding around these clever, cheeky and charming songbirds."
Picture Book Book Club (Instagram), 16 August 2022

"This glorious picture book written by Nicole Godwin will become a firm favourite of younger readers. The striking end papers and bold illustrations by Susannah Crispe will delight the reader and perfectly complement the simple yet captivating text."
Kathryn Beilby, ReadPlus, 01 September 2022

"Crispe's illustrations are simply stunning. With beautiful soft colours and details galore, in only one setting (Magpie's tree at the park). Crisp creates an entire world, with multiple characters that have stories of their own lovingly weaved into their expressions, clothing and accessories. It's truly a delight to turn each page, meet a new character and imagine who they are and what has brought them to the park."
Shayne Wardrop, Kids Book Review, 02 September 2022

"Coupled with explanatory notes at the end and thorough teaching ideas which cover science, English, ethics and Aboriginal and Torres Strait Islander histories and cultures, this is a book that must be shared with every young student so they understand why magpies swoop, and that they are just like human parents in their desire to keep their babies safe."
The Bottom Shelf, 04 September 2022

"I love the brevity of Godwin’s text, with short, punchy sentences and a pattern around repetition of the word 'swoop'. And in Crispe’s vibrant illustrations, Magpie’s bold, proud image, with animated facial expressions, occupies centre stage alongside the busy activity of the park visitors and set against soft greys and greens of a lush Australian park background. <...> I highly recommend this book for 6-9 year olds, especially as a teaching resource to introduce discussions about birds or animal behaviour in general. There are teaching notes on the publisher’s website."
Barbara Swartz, CBCA Reading Time, 19 September 2022

"While only around 10 per cent of male magpies actually attack, their seasonal antics have becomes a part of Australian folklore. Nicole Godwin's spare, carefully crafted text provides opportunities for young readers to join in Magpie's "swooping", while Susannah Crispe's watercolour illustrations perfectly capture the character of the cheeky magpie dad <...> This is a fabulous way to help young people appreciate a magnificent bird that is an important part of our urban environment."
Stephanie Owen Reeder, Canberra Times, 3 December 2022

The Vixen HF2-BT81S-A Astronomical Binoculars and Tripod are your perfect wide field viewing companions.

This complete kit includes everything you need to start exploring the night sky. Experience

• Stunning views of the Moon
• Large nebulae complexes such as the Great Orion Nebula (M42) and Etc Carina
• Globular and Open star cluster
• The star cloud of the Milky Way
• Our nearest satellite galaxies, the Large and Small Magellanic Clouds
• Plus more!

These large binoculars are equally at home looking up at the night sky or pointed at whales migrating along the coast or scenery in the distance.

The two adjustable eyepieces can be changed and accept any standard 1.25" telescope eyepiece to vary the magnification. (BINTEL has a vast range of these, and we can advise on your best options.) The sturdy tripod and easy to adjust mount means comfortable viewing, either seated or standing for extended periods of time.

If you're lucky enough to have a water or scenery views or want hassle-free night viewing, these Vixen binoculars and mount are ideal.

To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.
Example: RASA 8 with a ZWO ASI 183 MC PRO camera

• Required back-focus distance for RASA 8 with included M42 camera adapter: 25mm
• Back-focus consumed by ZWO ASI 183 MC PRO camera: 17.5mm
• To achieve equal back-focus distance, a 7.5mm M42 spacer ring is required

Celestron’s M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters.

How to Use
Depending your method of astrophotography (DSLR or CCD/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.

Below is a quick guide to help you determine which spacer ring to use for our EdgeHD, Schmidt-Cassegrain, and RASA 8 optical tubes:
