Introducing the ASI676MC, the all-sky camera featuring a unique square
1/1.6-inch image sensor and a super high resolution of 12MP! It is perfectly suited for meteor recording and full sky surveillance. The
square format facilitates easier composition, making mosaic stitch simpler and more efficient, and the high resolution brings you clear details of the Sun and our Moon. With this camera, you may start your marvelous journey
to explore the boundless night sky.

Why Square Format?

One of the biggest benefits of AS1676MC's square format is it makes the whole mosaic construction process much easier by eliminating the need to consider the difference between the long and wide
sides of the format during mosaic stitching. Not only that, the square format also makes the AS1676MC more compatible with various types of lenses such as fisheye lenses and wide-angle lenses. Thus,
ASI676MC is more suitable for tasks such as meteor
recording and full sky surveillance.

Starvis 2 Technology

STARVIS is a sensor technology developed by Sony that surpasses the sensitivity of the human eye. STARVIS 2 is an advancement of STARVIS technology,
supporting an even higher dynamic range. With this technology, ASI676MC exhibits lower readout noise and dark current, along with significantly enhanced
sensitivity in the near-infrared spectrum.

No Amp Glow

AS1676MC does not have any amp glow, no matter
how long the exposure and how high the gain value
you set.

256MB DDR3

The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3
cache to ensure stable and secure data transmission.

Higher QE Lower Readout Noise

The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at low gain. When the gain is 180, the HCG mode is automatically turned on. The readout noise is as low as 0.56e, and the dynamic range can still reach a level close to 11stops.

Quantum Efficiency 

The QE curve and readout noise 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 ASl676MC is about 83%.

Dark Current Noise

The ASI676MC's lower dark current noise means that the image signal-to-noise ratio is also higher, especially when photographing dark objects, it produces images with better sharpness.

IR-Cut Coated Window

ASI676MC is equipped with an IR-cut coated window in front of the sensor, with a diameter of 21mm and a thickness of 1.1mm. It effectively reduces infrared interference and improves image quality.

The saxon 8" DeepSky CT Dobsonian Telescope （203/1200） features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.

This beginner telescope is the retractable twin to the full-tube saxon 8" DeepSky Dobsonian Telescope and comes with the same specs of 203mm aperture and a focal length of 1200mm. Featuring a collapsible truss-tube dobsonian design, the optical tube can be retracted into a shorter length and locked down to ensure secure and easy transportation. This scope also comes with a paraboloidal primary mirror to eliminate spherical aberration allowing you to see wide-field views of the Moon, constellations and deep sky objects such as the Great Orion Nebula.

Assembly of the telescope requires no additional tools. You'll be pleased with how easy it is to use the saxon 8" DeepSky Collapsible Dobsonian Telescope with its Dobsonian mount. Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.

What is a Dobsonian telescope and why the tension control handle?

A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.

The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.

The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.

These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.

By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

• Next-Generation Imaging Sensor for Celestron Origin: Upgrade your system with Sony’s latest Starvis 2 color CMOS technology, offering improved resolution and enhanced sensitivity.
• Compact Pixels, Brighter Images: Small 2.0 μm2 pixels increase resolution while Starvis 2 technology boosts light conversion efficiency. The result: brighter, sharper images with more faint object detail revealed.
• Modern 16:9 Aspect Ratio: A wide, cinematic field of view perfectly matches smartphone and tablet screens, producing images that fill the entire display for a more pleasing view.
• Easy, Tool-Free Installation: Clear, step-by-step instructions guide you through attaching your new camera using Origin’s existing adapter and retaining ring—no prior experience required.

Reveal stunning detail in your deep-sky astrophotography with the Origin 678C—Celestron’s next-generation camera for the Origin Intelligent Home Observatory. Featuring Sony’s latest Starvis 2 CMOS technology, this high-performance camera delivers increased resolution and finer detail thanks to its smaller pixel size and enhanced sensitivity.

The Origin 678C Camera replaces the original Origin 178C Camera, giving you an upgrade in image quality. Whether you're imaging galaxies, nebulae, or star clusters, you'll capture more object detail in images that better fill your smartphone or tablet’s display screen.

It’s the perfect way to further enhance your Origin experience—and your astroimaging.

What’s New with the Origin 678C Camera

The Origin 678C Camera brings meaningful enhancements to your astrophotography experience. Here’s what you can expect:

1. Increased resolution
   Although both sensors are the same physical size, the IMX678C uses smaller 2.0 μm² pixels than the 2.4 μm² pixels in the IMX178C. This results in a finer resolution of 1.2 arcseconds per pixel (down from 1.5 arcseconds per pixel), allowing you to resolve more detail and “zoom in” slightly more on celestial objects. This is especially beneficial since most night sky targets are relatively small.
2. Larger file sizes
   Because the IMX678C packs more effective pixels (8.4 MP vs. 6.4 MP), image files will be somewhat larger. As a result, you may notice slightly slower automatic image processing in the app, depending on the performance of your smartphone or tablet.
3. Increased sensitivity
   Despite having smaller pixels, the IMX678C is slightly more sensitive overall than the IMX178C. The improvement is subtle; images won’t appear dramatically brighter.
4. Different ISO response
   ISO values are not directly comparable between the two sensors. The IMX678C's default ISO is 1000, while the IMX178C’s is 200.
5. Different aspect ratio
   The IMX678C uses a 16:9 aspect ratio, compared to the 3:2 ratio of the IMX178C. This means your field of view will appear more rectangular, ideal for framing larger regions of the sky and perfectly matched to the landscape orientation of most smartphone and tablet displays—making it easier to compose, view, and share your images.

Quick and Simple Installation

Upgrading to the Origin 678C Camera is fast and hassle-free. Designed to integrate seamlessly with your Origin system, the camera installs without any complicated tools or processes. Simply remove the existing camera, attach the Origin 678C using the included adapter and retaining ring, and plug it in.

After you install the new camera, we’ll walk you through capturing new calibration frames. Dark frames reduce sensor noise, while flat frames correct for illumination variations across the image. The Origin app makes this process simple and intuitive—and you can follow along with our video, too.

For the easiest and most consistent results, we recommend the PrimaLuceLab GIOTTO for Celestron Origin— a flat-field generator custom-designed for Origin that works with the same smartphone you use to control Origin. Whether you use GIOTTO or the evening sky (i.e., “sky flats”), capturing new flat frames ensures your upgraded system is optimized and ready to deliver stunning, high-contrast astrophotography from your very next session.

Second Life for Your Origin-178C Camera

Upgrading to the Origin 678C doesn’t mean your original camera has to sit on the sidelines. The Origin-178C is a powerful tool, and now it’s free to be used with other telescopes you may own. With its standard M42 T-thread connection, it mounts easily to most optical systems and makes a great planetary or lunar imaging camera. In minutes, your 178C will be ready for a whole new role in your astrophotography toolbox.

Let Lonely Planet take you further than ever before with the world's first and only travel guide to the Universe. Developed with the latest data from NASA, we take you from our home on Earth and out into the far reaches of the solar system, then into our neighbouring stars and planetary systems, and finally into the rest of our galaxy and the Universe.

This fascinating journey will help you explore space as you would the world with a Lonely Planet guide. Unique to these pages are wonderful comparisons of Earth with the other worlds of our solar system and even those exoplanets orbiting other stars.

You'll discover as much as we know about our celestial neighbourhood, and our place in it. In addition to planets and moons, get to know our Sun, explore the asteroid belt and the Kuiper Belt, and learn what lays beyond, in interstellar space. Outside our solar system, travel to some of the notable neighbouring stars, stellar systems and exoplanets we've discovered. You'll understand how we search for planets where life might exist and the stars they orbit.

Finally, discover the edge of the observable Universe. Get to know the structure of the Milky Way as well as an orientation to neighbouring galaxies like the Andromeda Galaxy which is visible from Earth. Then explore other galactic formations and learn about galactic clusters and superclusters. By the end of the book, you'll have a sense for the structure of the entire Universe as well as some of the big questions we still have as we ponder our place in it.

天文摄影市场缺乏可靠的 USB3.1 集线器，促使我们开发了 Pegasus Astro USB 控制集线器，它还可以打开/关闭每个 USB 端口。

我们自豪地推出 Pegasus Astro USB 控制中心（简称 UCH）：

超高速 (SS)、低功耗、可切换的 USB3.1 Gen1 集线器，完全符合 USB-IF 的 USB 3.1 Gen1 规范。该集线器支持高速 (HS)、全速 (FS) 和低速 (LS)。新的超高速集线器与 USB 2.0 控制器并行运行，因此 5 Gbps 超高速数据传输不会受到较慢的 USB 2.0 流量的影响。

6 个 USB3.1 活动端口

USB 控制集线器 uch_3-2
该设备有 6 个 USB 3.1 端口。所有端口均向后兼容 USB 1.0 和 USB 2.0 设备。

每个端口可提供高达 2.5 安培的电流。每个端口都有一个智能电流限制传感器，当出现短路或功耗超过 2.5 安培时，会自动限制或切断电源。

每个端口都由 USB 控制器监控，如果电流限制，它会在操作系统中触发警告弹出。

工业级温度支持

市场上的大多数 USB 集线器（嗯……几乎所有）都在室温下运行，因为它们是为在温暖舒适的房间内工作而设计的。这也是为什么在寒冷的夜晚你会遇到 USB 断开连接和不稳定的原因之一。

我们的产品经过认证，可在 −40°C 至 +85°C 的温度下完美运行。所有 USB 集线器电子产品均经过精心挑选，以支持工业级温度范围。
