From bestselling author and British astronaut Tim Peake, an inspirational human history of space travel, from the Apollo missions to our future forays to Mars. The Right Stuff for a new generation.

'This book is brilliant - once in a blue moon. A book for the whole family.' Chris Evans, Virgin Radio

'The most wonderful book ... Tim Peake is a historian and encyclopaedia of space.’ Rory Stewart

'An extraordinary book. For anyone - even if you’re not interested in Space. If you’re interested in human stories and the human character - this is delightful.' BBC Breakfast

'A fascinating, detailed, playful book drawn from extensive research – Peake met seven Apollo astronauts, Russian cosmonauts and various other space technicians – as well as his considerable personal experience. Lifts the lid on what space is like: the dedication and sacrifice; the politics and pantomime; the practicalities and the peril; the glory and fame; the adjustment back to normal life.' iPaper

'A thrilling human history of space' Daily Mirror

'The bible of space travel' Chris Moyles, Radio X

As seen in the major TV series Secrets of Our Universe with Tim Peake.

Only 628 people in human history have left Earth. This is their story.

Astronaut Tim Peake traces the lives of the remarkable men and women who have forged the way for humanity beyond Earth, from Yuri Gagarin to Neil Armstrong, from Valentina Tereshkova to Peggy Whitson.

Full of fascinating insight into our greatest pioneers and unsung heroes, and astonishing detail only an astronaut would know, Peake's book is the first of its kind to chronicle the human evolution of space exploration over sixty years, from our first forays to now. In the process, Peake reveals what spaceflight is really like: the wondrous view of Earth, the surreal weightlessness, the extraordinary danger, the surprising humdrum, the unexpected humour, the new-found perspective, the years of training, the psychological pressures, the gruelling physical toll, the thrill of launch and the trepidation of re-entry.

In the next few years, NASA will send the first woman and the first person of colour to step on the lunar surface. What will separate these upcoming moonwalkers from the legendary Apollo crews? Does it still take a derring-do attitude, super-human fitness, intelligence, plus 'the right stuff' - a fabled grace under pressure? And how will astronauts travel even further - to Mars and beyond?

Space: The Human Story reveals all.

'Space enthusiasts will snap up Peake’s compelling book in their droves, but his account of courage,
camaraderie and the determination to go where few have gone before deserves to be read by a much wider audience too' – Daily Express

Viewed straight through, you see the natural sky with a 10 arc-minute (1/3 Moon diameter) "red-star" showing your scope's position. When your scope is pointed high, flip the mirror into position for more comfortable viewing. Viewed this way, the sky orientation matches a refractor or SCT's image. The adjustable brightness and blink-rate of the "red-star" makes it easy to see against any twilight to dark sky background.

With its 39mm aperture, the projected image is easily seen any distance behind Starbeam, whether 2 inches or 2 feet! The finely made glass lens acts as a beamsplitter to combine the natural sky background with the superimposed red pointing "star." The first lens surface acts as a collimating mirror so the "red-star" stays stationary against the sky background regardless of how it is viewed. It's 6-arc-minute accuracy over any eye position allows you to pin-point objects -- even with high-power eyepieces in the telescope. A compensating curve is designed into the second lens surface to provide the normal sky background view and is multi-coated to eliminate double images.

Elegant in design and form, Starbeam is custom machined completely from aluminum and then black anodized, even down to the "push-pull" thumb screws. No tools are required to align Starbeam with your telescope. Mounting hardware included.

• Cleans cameras, lenses, spotting scopes, screens & binoculars
• Effectively removes fingerprints, grease, dust & dirt
• Suitable for wet & dry cleaning
• Includes lens air blower, brush, swabs, lens tissue book & polyester cloth

Capturing the most stunning astrophotographs possible is something our team is passionate about. From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 20″ telescope was centered around performance and ease of use. The Planewave CDK20 f/7.7 OTA is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK20 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK20 is an exceptional diffraction-limited telescope. CDK20 users can experience pinpoint stars edge-to-edge and a 45 x 45 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!

Pentax's highly portable and functional U-Series UP Compact Binocular employs an innovative unibody design that locks the objective lenses into the body with the eyepieces set on a synchronized dual-axis mechanism that ensures they stay symmetrical in relation to the center axis of the optic when adjusting the interpupillary distance. The 25mm objective lenses are fully multicoated to reduce reflection and maximize light transmission to produce the brightest images possible. Aspherical lens elements virtually eliminate distortion, especially around the edges, and corrects for lens astigmatism which can prevent sharp focusing.

Designed for easy carrying and stowing, the binocular features a lightweight fiberglass reinforced polycarbonate housing that is corrosion and impact resistant. The housing material is also temperature-resistant allowing for its use in extreme climates while reducing expansion and contraction wide temperature variations can cause, which can make the optical components move out of collimation over time.

The Celestron PowerSeeker Accessory Kit is a great way to expand the enjoyment of your telescope. Inside the plastic, foam-lined carry case you’ll find these accessories:

• 15mm Kellner Eyepiece - 1.25”
• 9mm Kellner Eyepiece - 1.25”
• #80A Blue Filter - 1.25”
• #25 Red Filter - 1.25”
• Moon Filter - 1.25”
• Microfiber Cleaning Cloth

Eyepieces - The 15mm and 9mm eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 9mm provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

Filters - Coloured filters can be used to bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

• The #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the color shift.
• The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It’s also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.
• The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it helps you see which phase she’s in.

Cleaning Cloth & Case - Keep the microfiber cleaning cloth stashed in your PowerSeeker Accessory Kit case so that it will always be handy. It’s better to use a microfiber cloth on your optics than wipes or tissue, as it will not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you’ll keep them looking and performing like new.

One of the issues faced by those using wheelchairs, is that they're frequently using their hands for pushing it.

To assist in the comfortable use of a phone, tablet, binoculars or even a DSRL camera when using a wheelchair, the Kenko Assist ARM series firmly attaches your device to the wheelchair, freeing your arms and hands.

https://www.youtube.com/watch?v=e3euenuEh9M

The mount is solid too, greatly reducing the risk of unexpected movement of or even dropping your device. The angle and height can be freely adjusted to suit you and the KS-WL has an extension pole can be attached to extend the range of motion.

The Assist ARM series is accessories that was developed in collaboration with the camera tripod manufacturer SLIK.

In the recent years, as cameras have become increasingly sophisticated and precise in terms of technology, the camera industry demands greater and more secure support of such high-precise photographic equipment. One of the tools that can provide such secure support are of course tripods.

By teaming up with SLIK, a company that has a long tradition in making strong tripods for all kinds of cameras and that can withstand all kinds of environments, we were able to bring in their know-how and technology when designing the "Assist ARM" series, making it an accessory with high precision and outstanding stability.

Therefore, Kenko Assist ARM is designed not only to eliminate inconveniences when moving with a wheelchair, but also to ensure maximum user safety.

Firm and safe attachment for safety and convenience

The clamp that can be attached to the pipe of the wheelchair is made of aluminium and is very robust, so the risk of it suddenly coming off when the wheelchair is moving is extremely small.

The clamp can be attached to round pipes (17-32mm) and square pipes (Square: 22-28mm, Rectangle: short side 15-25mm / long side 25-28mm).

* When attaching to a pipe with a diameter of 17-22mm, a rubber tube (included) has to be used for a firm grip.

UNIVERSAL BALL-HEAD PROVIDES FREEDOM FOR ADJUSTMENT AND QUICK SET-UP

A universal ball-head provides freedom and allows precise adjustment.

The quick-release shoe also makes for a smooth set-up of gadgets such as iPad, iPhone, cameras, binoculars, and so on.

Starvis 2 Technology

If you're not familiar with SONY STARVIS technology it offers the ZWO ASI664MC outstanding image quality and image performance.

High Transmission Speed

This camera has a USB 3.0 Interface, along with the built-in 256MB DDR# cache, ensuring high-speed, smooth, and stable data transmission.

ZWO ASI664MC vs ZWO ASI662MC

ZWO ASI664MC can be considered as an iteration of the ASI662MC. With the great improvement in sensor size and resolution, it provides a larger FOV and results in high-quality images containing more details.

Zero Amp Glow

ZWO ASI664MC adopts no-glow circuitry to avoid annoying amp glow being produced and ensure the image quality no matter how long the exposure and how high the gain value is.

(NOTE: This feature is implemented directly at the hardware level, it does not require software control.)

Camera Curve

Low readout noise, high dynamic range

The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain and keep the dynamic range at the same level as it does at low gain. At 252 and above the HCG is automatically turned on; the dynamic range is close to 11bit; the readout noise can be lower than 1.0e.

Quantum Efficiency

QE noise and readout are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio. according to our estimation, the QE peak value of the ZWO ASI664MC is about 91%

Protective Window

The ASI664MC adopts an AR-coated filter as a protective window (Diameter: 21mm, Thickness: 1,1mm). It improved the camera's performance in UV and NIR wavelengths.

PLEASE NOTE: This version of the Celestron Origin Intelligent Home Observatory is no longer available

Check out the new Mark II version here

Celestron Origin stands at the forefront of a new era in amateur astronomy, blending stargazing and astrophotography into a single, user-friendly experience. This intelligent, all-in-one home observatory takes the complexity out of traditional telescopes, transforming your backyard into a gateway to the cosmos. Packed with cutting-edge technology, Celestron Origin captures the beauty of celestial objects and brings them to life on your phone or tablet.

Celestron engineers drew on their decades of expertise while designing every detail, from Origin’s patented optical technology to its intuitive companion app. The result is a revolutionary new system that builds on Celestron’s legacy and makes astronomy more accessible, exciting, and fun than ever before.

RASA Optical Technology: Unleashing the Power of Light

At the heart of Celestron Origin lies the patented Rowe-Ackermann Schmidt Astrograph (RASA)—a landmark advancement in optics. In the RASA design, the imaging sensor lies at the front of the telescope tube, not the back, creating an ultra-fast f/2.2 system with an extraordinarily wide field of view while providing sharp images to the edge. Since it launched in 2014, RASA technology has become the go-to choice for space surveillance and satellite tracking. National defense contractors, professional research astronomers, and governments trust RASA to detect tiny pieces of debris and space junk, keeping our vital communications satellites safe in orbit. For Origin, Celestron’s optical engineers developed a brand-new 6” RASA with all the same capabilities of an observatory-grade instrument in a grab-and-go package.

Thanks to RASA, Origin is in a class of its own, far outperforming other telescope designs. RASA simply delivers more photons in less time than a smaller and slower Newtonian reflector, refractor, or other entry-level telescope tube. RASA’s unique combination of speed, aperture, and performance ensures unparalleled image detail, even during short exposure times.

To take full advantage of the RASA optics, Celestron selected the Sony IMX178 color CMOS sensor to capture your data. It features STARVIS back-illuminated technology for the highest sensitivity and fast readout with low noise, helping to provide clear images as quickly as possible. This sensitive chip has small 2.4µm² pixels for high resolution—a perfect match for the fast optical design.

Turning Every Backyard Observer into an Astroimager

Celestron Origin introduces a paradigm shift in astrophotography with its built-in AI algorithms. As the telescope captures data, these intelligent algorithms automatically stack and process every frame in real time. The result is a breathtaking display of celestial objects, rich with colour and detail. For the first time, astroimaging is accessible to enthusiasts of all skill levels, including those who have never used a telescope.

A Universe at Your Fingertips: StarSense Technology & the Origin App

Setting up Celestron Origin is a snap, thanks to its automated initialization process powered by StarSense technology. Place Origin outside, turn it on, and connect to the app. Then, you can choose to remain with your telescope or head indoors. In less than two minutes, Origin focuses itself, scans the night sky, autonomously aligns itself by matching star patterns overhead to its internal database, and notifies you that it’s ready to begin your astronomical adventure.

The Celestron Origin app, developed in collaboration with Simulation Curriculum, the makers of SkySafari™, offers an intuitive planetarium interface that simplifies navigation through the night sky. Using the planetarium view, hold your device up to the sky to look around using “compass mode”, and tap on any object you want to see (the best ones are highlighted). Or try the Tonight’s Best list, where Origin displays all the most impressive galaxies, nebulae, star clusters, and more—based on your precise location and observing time. Forget about consulting a star chart or planning ahead; Origin is ready to show you the universe whenever you are.

Once you’ve chosen a target, Origin centres it precisely in the field of view. Switch to the camera view and press Start Imaging to begin capturing 10-second exposures. It’s that easy! You see the results come through in real-time as the target takes on more and more detail. As Origin works, it continually tracks the sky and adjusts its built-in dew prevention system to keep your images razor-sharp.

A Shared Cosmic Experience

Gone are the days of waiting in line to peer into an eyepiece. Origin fosters a sense of community as you share the awe-inspiring experience of exploring the night sky together. Whether your friends and family are in the same room or gathered outside, multiple people can connect to Origin, and stream the view with their own devices. Additionally, Origin allows you to cast the live feed to your smart TV or instantly save and share your astroimages, creating memorable moments beyond the confines of your backyard.

Ready for More? Advanced Features

As you grow in the hobby alongside Origin, it will continue to support you with more advanced features and functionality. For example, Origin has a built-in filter drawer that accepts standard 1.25” and 2” format filters. This allows you to install optional filters, which can be especially useful in imaging nebulae in light-polluted environments like the typical suburban backyard. For imaging broadband objects like galaxies and star clusters or objects from dark skies, remove the filter for more light-throughput and brighter images. Experiment with removable and interchangeable filters for results you can’t achieve with other systems’ fixed filters.

If you would like to try advanced image processing, Origin again has you covered. Unlike other systems, Origin stores all your RAW images for you. Connect via USB to import them into your favourite image-processing software for manual editing and stacking.

And how about putting Origin to work for you while you sleep? That’s no problem with the scheduled observations feature. Just tell the app which objects you want to capture. You’ll wake up to an array of spectacular images.

Gain a New Perspective Here on Earth

In addition to revealing distant worlds, Origin can also capture incredible views of land-based objects on Earth, day or night. During the day, you can manually slew Origin to capture landscapes and scenery. At night, Origin’s fast optics and sensitive camera allow you to see things in very dim ambient conditions for almost night vision-like performance. Look around your yard or campsite at night to see what you may be missing!

Take Your Astroimaging Studio Anywhere

Origin is a portable system that doesn’t require external Wi-Fi networks, so you can easily take it to remote dark skies in any car. The optical tube, mount, and tripod all easily assemble and disassemble without tools. Each component weighs less than 7.5kg. Optional carry cases are also available.

Your Origin system comes complete with everything you need to become an instant astronomer:

• 6” RASA optical tube with integrated camera
• Origin single fork-arm mount with internal lithium battery
• Built-in computer with cooling fans and WiFi
• Autofocuser
• Dew prevention system with environmental sensor, dew heater ring, and dew shield

Power Information

Enjoy the most dazzling views of nebulae with your Celestron Origin when you add this H-alpha H-beta OIII (Hα-Hβ-OIII) imaging filter. This specialized filter allows high throughput of light wavelengths in emission nebulae while blocking other wavelengths that could diminish image quality and detail. The result is bright, colorful nebulae images that “pop” with detail against the black sky background.

How does the Nebula Filter for Origin work? Emission nebulae primarily emit at discrete wavelengths of light—Hα at 656nm, Hβ at 486nm, and OIII at 496/501nm. By strategically transmitting only these wavelengths of light and blocking the rest of the spectrum, the filter dramatically reduces the effect of light pollution. The “bad” light is blocked while the “good” light associated with emission nebulae passes through to Origin’s sensor.

You’ll immediately notice much higher contrast in your images, especially from your light-polluted backyard! And since the transmission at the critical wavelengths is so high, the nebula will not be dimmed—only the background will be blacker. You’ll also notice some contrast improvement in images of nebulae from darker skies, as the filter serves well in blocking natural skyglow.

Nebula Hunting

The Nebula Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), the Carina Nebula (NGC 3372), and dozens more. The imaging filter offers maximum light transmission in the key Hα-Hβ-OIII wavelengths, producing high contrast for emission nebulae like these.

The transmission spectrum for the Nebula Filter is 85% or greater at key wavelengths (486nm, 496nm/501nm, 656nm) and less than 0.5% transmission elsewhere. As a narrowband filter, it blocks much of the visible spectrum and only lets these specific wavelengths through. Because of this, you should not use this filter while observing or imaging broadband emission objects, such as galaxies and star clusters. For those objects, you’ll achieve the best results by removing the nebula filter and reinstalling Origin’s clear optical window.

Other similar imaging filters on the market have much narrower bandpasses at the critical Hα-Hβ-OIII wavelengths. Unfortunately, these filters block much of the incoming Hα-Hβ-OIII light for an f/2.2 optical system like Origin’s 6” RASA. This is because a RASA brings light into the filter at a steeper angle, which causes a spectral shift. If you use filters not explicitly designed for use at f/2.2, some of the light from the nebula will be blocked, resulting in a dimmer image. The Nebula Filter for Origin was custom-engineered to work at f/2.2, so none of the “good” light from the nebula is inadvertently blocked by the filter.

Body and Storage

The filter features a machined aluminum black anodized cell with a knurled rim for easy grip during installation. We’ve added anti-reflection coatings to help suppress reflections on the glass. The filter fits directly into the filter drawer in the Celestron Origin’s front lens cell, where the optical window sits. Simply remove the clear window and replace it with the filter. Origin maintains its optical performance across the entire system with the filter installed. No other adapter is needed.

Each filter comes with a foam-lined plastic storage case to safely store the filter or the optical window glass that came with your Celestron Origin when not in use.

Celestron tests every Nebula Filter for Origin individually to verify its performance. Along with your filter, you will receive a spectral transmission graph (like the one pictured above) showing the results of your filter’s test and verifying it performs as expected throughout the spectrum.

The Telrad is already the best accessory for a telescope. The Telrad Pulsear Kit allows you to pulse the reticle on and off, making it easier when trying to locate very faint objects. It requires some installation where you will need to drill a 6mm hole into the side of theTelrad body to install the Pulsars control shaft and knob. This allows you to vary the frequency of the pulsing from slow to constant illumination.

Fitting instructions are included.
