ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras. The Duo-Band filter is aimed at the astronomer who may already own a One Shot Colour (OSC) camera and wants to image using narrowband techniques or emission objects without purchasing a mono camera, filter wheel and narrowband filter set.

The Duo-Band filter offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.

The dual band pass nature of the Duo-Band filter passes light at Hα (656nm) and OIII (500nm) wavelength, and can reduce the interference from natural light sources such as moonlight, or artificial light pollution such as street lighting.

It can help improve the contrast and visibility of deep sky objects such as emission nebula using a OSC (One Shot Colour) camera.

If you are looking for a solution to deep sky photography in light pollution area, then ZWO Duo-Band Filter will be a great choice.

The Duo-Band filter can be used with all ASI cameras and EFW Electronic Filter Wheel and comes in 1.25” and 2” sizes.

The Celestron Off Axis Guider is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible. The Celestron Off Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star. Any movement seen by the guide star will be the exact same movement seen by the imaging camera. Guiding this way will correct for tracking errors, as well as opto-mechanical errors or flexure. The result: better astroimages with pinpoint round stars.

Off Axis Guiders have been around for a long time, but typically pose three main challenges:

Finding a guide star from the far edges of the telescope’s focal plane can be difficult, considering the small field of view and sometimes less-than-ideal illumination.
Getting both imaging camera and autoguider to reach focus with one another is time consuming and sometimes requires experimentation.
Additional spacers and adapters are usually required for your particular camera, telescope, and autoguider, which adds to cost and complexity.

The Celestron Off Axis Guider addresses these challenges by:

Providing a large 12.5mm prism that can be adjusted to move closer to the center of the telescope’s focal plane, depending on the size of the imaging camera. This results in brighter guide stars, with the help of the large prism to fully illuminate the autoguider sensor.
Featuring a high-quality, fixed-orientation Helical focuser. This provides extremely smooth and accurate focus of the autoguider without changing (or twisting) the autoguider camera orientation.

Including all the needed spacers and adapters are included for most common imaging configurations, including DSLR cameras, Nightscape CCD cameras, and more. The following adapters are included: SCT/EdgeHD, female M48, female M42 (T-thread), male M48, male M42 (T-thread), 3 T-thread spacers

Additonal Specifications

The NEW ZWO ASI 662MC One Shot Color Camera with High Sensitivity

The new ZWO ASI 662MC adopts the Sony IMX662 sensor, has a rolling shutter, a frame size of 1/2.8", and a pixel size of 2.9um, and has 2.07million pixels (1920 x 1080). In high-speed mode, the CMOS sensor can output 102.6 frames per second at full resolution and provide a low read noise level.

Large Full Well capacity, not easy to overexposure

The ZWO ASI 662MC adopts the Sony 662MC sensor with the latest technology. Compared to the previous generation of sensors, it has a very low readout noise and extremely large full well capacity which is 3 times larger than that of the IMX462MC. This helps effectively with overexposure issues and allows longer exposure s. In low light conditions, the camera performs excellently, capturing very clear images of celestial objects.

STARVIS 2

ZWO ASI 662MC adopts the latest Sony IMX662 sensor with advanced STARVIS 2 technology. Featuring zero amp glow, higher sensitivity to red and Near Infrared (NIR) light, 3 times the full well capacity. it can be regarded as an upgrade of the ASI462MC. Also, its dark current noise is several times lower than the ASI462MC.

USB3.0 and 256M DDR Memory

The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR 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.

No Amp Glow

ZWO ASI 662MC 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.

300 Second exposure with ASI 462MC

300 Second exposure with ASI662MC

Quantum Efficiency

The QE curve and noise 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.

Camera Curve low read noise, high dynamic range

Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better. As can be seen, the readout noise of the ZWO ASI 662MC is very low compared to CCD camera. The built-in HCG mode can effectively reduce the readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 252, the HCG mode is automatically tuned on and the dynamic range rises back to 12-bit.

What's in the box

Celestron has joined forces with master lunar cartographer Ralph Aeschliman on a two-sided Moon Map. This quality map provides you a great way to familiarize yourself with the Moon, our neighboring world. Whether you are looking for Lacus, Maria, Montes, or Valles, the Moon map will help you navigate the lunar landscape with confidence. You can observe features with your telescope and locate them on the map or vice versa. This map also features a directory of all the key lunar regions with coordinates to find them.

On the reverse side of the map, there are close-up photos and information about the most exciting lunar regions to explore. You’ll also find images of the North and South polar regions for reference​. Refer to the lunar observing tips for practical information about using your telescope or binoculars to explore the Moon.

The Observer's Map of the Moon is waterproof, tear-resistant, and can be folded into an 20cm x 10cm size, making it easy to take along on your next camping trip, star party, or evening in your backyard. When not in use, the Moon map will be a stylish decorative poster on your wall. It makes a great display for your classroom or astronomy club.

Whether you are just beginning or an advanced observer, you will find yourself viewing the Moon again and again; have the Observer's Map of the Moon be your guide.

Eyepieces - The 15 mm and 6 mm 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 15 mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 6 mm Plossl provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2x Barlow Lens - Insert the 2x Barlow Lens between the eyepiece and the telescope and it doubles the magnification of any 1.25” eyepiece. That means the 15 mm Kellner included in this kit will double in power, effectively becoming a 7.5 mm eyepiece, and the 6 mm will provide the magnification of a 3 mm. Any other 1.25” eyepieces you already have will also work in this versatile accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for you and your telescope. T-threads are machined into this Barlow lens, allowing a user to attach a DSLR camera with the addition of an optional T-ring.

Filters - Colored 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 the planet’s phases.

Cleaning Cloth & Case: Keep the micro-fiber cleaning cloth stashed in your AstroMaster Accessory Kit case so that it will always be handy. It’s much better to use a micro-fiber cloth on your optics than other wipes or tissue, as it does 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.

ASI174MM Mini camera integrates Sony IMX174LLJ / IMX174LQJ 1/1.2″ sensor (11.3 mm x 7.1 mm). It is the first model in the “mini”-series of cameras from ZWO. This camera has 1936 x 1216 pixels with a pixel size of 5.86 μm x 5.86 μm.  It camera provides 12-bit ADC and its QE peak is 77%.

Astrophotography Performance

ASI174MM mini camera offers you very good performance for planetary imaging as well as for guiding. Low read noise, high dynamic range, AR protective window and much more are just some of the key characteristics that set it apart from the competition.

USB2.0Port & ST4 Port

USB 2.0 Port: Mini camera has one USB2.0 type-C port. Type-C port is very popular in mobile phones, as it doesn’t matter which way you connect it (unlike for example type-A or type-B)

#USB-C to USB-A cable is required.

ST4 Port: The camera can be connected directly to the auto-guider port of the mount.

High Sensitivity

Sensitivity is the first thing we considered. This is of course a crucial ability when looking for a star to guide on. So, from the beginning, we were set on using monochrome sensors to design our guide cameras. Because monochrome sensors have much higher sensitivity than their colour counterpart. Luckily the ASI120MM Mini, ASI290MM Mini and ASI174MM Mini all have very high QE peak value – about 80%, which can detect more stars in view and shorten the exposure time in guiding.

Each of the cameras have their own strength and depending on what you value in a guide camera, one might be better for you than the others.

What's in the Box

ZWO 1.25″ IR 850nm Pass Filter suitable for IR sensitive cameras. You don’t need to debayer and get the full resolution of this sensor when use it with a Color camera such like ASI224MC or ASI185MC. Because the QE responce of sensor beyond 850nm is all the same. So you can use a color camera as mono camera with this filter, just don’t forget to keep the WB_R and WB_B to 50 (no White Balance applied).
