ZWO ASI6781MC

ZWO ASI678MC adopts Sony's Latest generation sensor IMX678 with excellent near-infrared response. With the advantages of Large full well capacity, high dynamic range and low readout noise, this camera has been tested and found to have perfect performance in planetary imaging, solar and lunar imaging.

Clear in low light

Thanks to the back-illuminated sensor structure and advanced pixel techno[ogy, the camera has very low readout noise and an ultra-high sensitivity. Especially in Low light conditions, the camera performs very well and is able to capture very clear images of celestial objects.

STARVIS 2

ZWO ASI678MC can be regarded as an upgrade of ASI178MC. It adopts the latest SONY IMX678 sensor with advanced STARVIS 2 technology. Compared to ASI178MC, this camera features zero amp glow, lower readout noise and higher sensitivity. The dark current noise is greatly decreased; the performance of near-infrared is greatly improved.

USB 3.0 & 256M DDR3 Memory

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. Under Long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.

Upgraded Model

The ZWO ASI678MC is an upgraded product of the ASI178MC. Compared to the ASI178MC, the ASI678MC has lower read noise, lower dark noise, and no amp glow.

No Amp Glow

ZWO ASI678MC exhibits zero amp glow, no matter how long the exposure and how high the gain value is. Since it is implemented directly at the hardware level, it does not require software control.

HCG Mode

The camera has a built-in I-ICG 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 [ow gain. When the gain is 182, the I-ICG mode is automatically turned on. The readout noise is as low as 0.8e, and the dynamic range can still reach a level close to 12bit.

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and tower readout noise are necessary to improve the image signal-to-noise ratio.

Dark Current Noise

ASI678MC has much lower dark current noises than ASI178, bringing it has better image signal-to-noise ratios. If we compare the darks frames captured with these two cameras, it can be easily found that the frame from ASI678 has much Less noise and rooks much smoother.

SKU: ZWO-ASI678MC

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.

The Saxon 10" DeepSky Dobsonian Telescope requires no additional tools during assembly and is incredibly easy to use, making it the perfect scope for beginner astronomers.

What is 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.

Binoculars for the great Australia Outdoors!

Pentax's 10x50 S-Series SP Binocular features large oversized fully multicoated 50mm objectives to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities, and its high 10x magnification provides an immersive observation experience whether users are bird watching or comet hunting.

Fully-multi-coated optics assure maximum light transmission resulting in high quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view. Aluminum-diecast body adds strength and durability. View your subjects even in dim light with high-quality BaK4 prisms that transmit more light at the edges to enhance illumination.

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 9.25" Celestron Schmidt-Cassegrain and EdgeHD optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

Work smarter, not harder, when it comes to combating dew. The Smart DewHeater and Controller 2x prolongs your battery life by optimizing power usage for up to two dew heaters. The controller gathers and analyzes information in real time to warm your optics just enough to prevent dew.

The Smart DewHeater and Controller comes with two ports to control two dew heaters at once. You can use one port to heat your optical tube while the other warms a second optical tube, a guide scope, an eyepiece, or another accessory. The controller also features an additional 12V DC output port so you can power another 12V DC device, such as your mount.

The Smart DewHeater and Controller works seamlessly with Celestron’s Dew Heater Rings, which have a built-in thermistor to provide temperature readings of the corrector lens. Third-party dew heater bands or straps are also compatible; you simply need to add Celestron's Thermistor for Smart DewHeater Controllers (sold separately).

Smart Controls

At the heart of the controller is a powerful microprocessor that gathers information from the sensors, computes the data, and automatically adjusts your dew heaters. The controller monitors the ambient temperature and humidity using its integrated environmental sensor and monitors the heaters’ temperatures using thermistors.

You can run the Smart DewHeater and Controller 2x as a standalone accessory. Or, if you want to view data from the controller and make manual adjustments, you can connect it to your Celestron telescope’s hand control or your PC. The controller works with NexStar+ or StarSense hand controls running the latest firmware or Celestron CPWI telescope control software, included with every Celestron mount.

Power

The Smart DewHeater and Controller 2x runs on a 12V DC battery (like our PowerTank Lithium Pro or PowerTank 17) and can handle a maximum power of 120W (10A max current @ 12V DC). The controller also features a 12V DC output port. You can use this extra port to power another device, like your mount. This way, you can power your entire setup from a single source. Resettable electronic fuses prevent damage if input or output current draw becomes too high.

NOTE: If you are using two dew heaters in heavy dew conditions and powering a 12V DC device, the controller may be operating near its power limit. In this case, one PowerTank Lithium Pro or PowerTank 17Ah will not have enough capacity to run your setup all night; you'll need a larger capacity battery or multiple batteries.

Unique Industrial Design

The Smart DewHeater and Controller 2x features a heavy-duty metal housing. Inside, a cooling fan protects the controller’s electronics.

The Bridge – On top of the controller, you will find the bridge, which is home to the device’s status LEDs and environmental sensors. It also helps with cable management. We have positioned the temperature and humidity sensors here, away from the control box and other components that could generate heat. Unlike competitor products, our sensors do not require additional cables to obtain accurate readings.

The LED lights on the bridge indicate the device’s current status. The LEDs provide warnings if the controller is drawing more current than your power source can supply or if the battery charge needs recharging. You can dim the lights if you are under dark skies.

Mounting – The Celestron Smart DewHeater and Controller 2x mounts on your CGE or CG-5 dovetail with the integrated dovetail clamps. If you prefer to mount the controller on your tripod leg, use the included strap.

Smart DewHeater and Controller 2x comes complete with:

• Smart DewHeater and Controller 2x
• Tripod leg strap
• Controller power cable
• Power cable for external 12V DC device
• AUX cable for connecting to Celestron mounts
• Thermistor extension cable to attach to Celestron’s Dew Heater Ring

Enhance your setup

We highly recommend pairing this controller with Celestron Dew Heater Rings. They fit seamlessly on your Schmidt corrector lens and will improve your observing or imaging year-round.

For the highest level of dew prevention, we also suggest adding a dew shield to your setup. While not required, a dew shield will cut down on the amount of power the controller needs to provide to the dew heater rings to keep your optics clear.

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:
