81057 NexYZ DX Smartphone Adapter Kit by Celestron

The NexYZ DX Kit is a great first step into the world of astroimaging or digiscoping. You get everything you need to capture sharp, detailed images and video: the customer favorite NexYZ smartphone adapter and a Bluetooth shutter release remote.

Patented NexYZ Smartphone Adapter

The NexYZ fits any eyepiece from 35mm to 60mm in diameter, including telescopes equipped with 1.25" or 2" eyepieces, spotting scopes, monoculars, and binoculars. NexYZ also attaches to microscopes with the addition of an included adapter ring, which takes the usable diameter down to 25mm, the size of a standard microscope eyepiece.

The NexYZ DX Kit accommodates a wide range of smartphones including the larger "phablets" like the iPhone 8 Plus and latest Samsung Galaxy devices. The phone platform is fully adjustable and can fit any device–usually with the case still on. The secure platform stands up to the weight of these heavier devices with ease, thanks to NexYZ's strong metal spring and threaded twist lock. Should you need to tighten the tension on each axis for a customized secure connection, click the Support & Downloads tab to read our NexYZ Tension Adjustment Guide.

Bluetooth Shutter Release Remote

To capture the best image, this kit also comes complete with a Bluetooth shutter release remote, which allows you to trigger the camera's shutter on any Android or iOS smartphone without touching the device's screen or buttons. This eliminates blurriness in your images caused by the phone or telescope shaking due to pressure from pressing the button manually. Pairing your Bluetooth remote to your smartphone for the first time takes only seconds. Detailed instructions are in our quick setup guide.

Easy as X-Y-Z

What makes patented NexYZ different from other smartphone adapters? The three-axis adjustment. Most adapters rely on you placing your phone perfectly on the platform and only offer limited adjustment in two axes. But NexYZ gives you the power to place your phone on the platform, center it over the eyepiece with the X and Y knobs, and then move up or down over the eyepiece until you have the entire field of view in your shot.

And even though this adjustment is ultra-precise, it's still quicker and easier than with other adapters. From start to finish, the process only takes about 30 seconds, including the time it takes to insert the phone into NexYZ, attach NexYZ to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs.

Switching phones, eyepieces, or optical instruments, requires only slight adjustments to re-center the camera over the new eyepiece. If multiple people want to capture a shot through your optic, NexYZ's simple spring-loaded clamps make it easy to remove one device and replace it with another in seconds. NexYZ is the ideal solution for star parties and group bird walks where everyone wants their own shot of the action.

You can also switch your image from portrait to landscape simply by turning the padded eyepiece clamp and readjusting the X-, Y-, and Z-axis to realign your phone with the eyepiece.

NOTE: NexYZ is compatible telescopes, spotting scopes, binoculars, monoculars, and microscopes. It does not fit riflescopes. NexYZ works with most phone cases, but if you have an especially large phone case with built-in batteries or a folio-style case, you will need to remove it.

• A complete digiscoping solution: NexYZ connects your smartphone to an eyepiece while the Bluetooth shutter release button helps you get a steady shot every time.
• NexYZ's patented design works with telescopes (with most 1.25" or 2" eyepieces), spotting scopes, binoculars, monoculars, and microscopes (with the included adapter rings).
• Connect the remote shutter release to your phone via Bluetooth to take photos or start/stop video recording without unwanted vibration.
• Both devices work with virtually all smartphone models, including the latest devices from Apple, Samsung, and Google.
• NexYZ features three directional knobs (X-, Y-, and Z-axis) that perfectly align your phone's camera with the eyepiece in seconds. In addition, you can make tension adjustments to keep the phone firmly in place.
• NexYZ stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body.

93640 1.25" Universal Barlow and T-Adapter by Celestron

If you'd like some flexibility in your astrophotography set-up, consider the Celestron Universal Barlow & T-Adapter (93640). This 1.25" accessory can be used three ways: as a 2X Barlow for visual use, as a prime focus T-adapter, or as a Barlowed" T-adapter for double the magnification and the benefit of extra inward focus travel.

The Universal Barlow & T-Adapter can be used as a 2X Barlow right out of the box. Insert any 1.25" eyepiece into the chamber and you'll enjoy double the magnification, while retaining all the eye relief of the inserted eyepiece.

The Celestron Universal Barlow & T-Adapter can also be used for prime focus photography, which means you use the telescope as a photographic lens a very big photographic lens! Just unscrew the bottom section of the unit to remove the Barlow and slide the chrome barrel into the telescope's 1.25" focuser or adapter. Lock it firmly in place with the focuser or adapter thumbscrew. T-threads on the top of the adapter screw into a T-Ring (sold separately) that is designed to attach to the brand-specific mounting flange of your DSLR or SLR camera.

Please note that some telescopes, especially "fast" refractors and Newtonians, may not have enough focus travel to allow the photographic image to come to focus when used in prime focus mode. In these instances, adding the Barlow to the T-Adapter will allow the telescope to reach focus. In "Tele-Extended" mode, the Barlow doubles the focal length and f/ratio of your telescope, resulting in an image on the sensor or film plane that is twice the size of a prime focus image.

Prime focus and tele-extended photography are popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

• The Celestron Universal Barlow & T-Adapter is three accessories in one!
• 2X Barlow: Use during visual observing to double the magnification of every 1.25" eyepiece you own.
• Prime Focus Photography: Use the T-Adapter portion of this accessory to transform your telescope into a giant telephoto lens.
• Tele-Extended Photography: Use the T-Adapter with Barlow to get double the magnification of prime focus mode.
• T-threads accept camera brand specific T-Ring (sold separately).

This Celestron filter set includes the following colors:

• 12 Deep Yellow - A good general purpose filter for smaller aperture telescopes (less than 4.5"), the #12 Yellow will improve the contrast of features on the Moon. It will also help you see the equatorial belts on Jupiter and Saturn, clouds and the polar ice caps on Mars, and the dusky detail on Uranus and Neptune.
• 21 Orange - Sharpens the boundaries along the plains of Mars due to the reduction of blue/green transmissions. Use on Jupiter and Saturn to enhance detail in the belts and polar regions.
• 80A Blue - 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.
• ND-96-0.3 Neutral Density - A great filter for the Moon, and for stacking with other planetary filters to increase density without changing the color. A neutral density filter is also useful when splitting binary star systems (double stars). Use anytime you want to decrease brightness but don t want to affect the color characteristics of an object.

Each Celestron 1.25" filter has 26 mm of clear aperture, and is mounted in a black anodized aluminum cell that is threaded on both sides. Double threads allow the user to stack different filters together to create a custom color or affect the transmission percentage.

94315 Moon Filter Set, 1.25" by Celestron

Our Moon is the most popular object to observe with a telescope. It's an obvious target that's easy to locate and full of exciting geographical features to explore. Moon filters enhance lunar viewing by cutting down on the Moon's bright glare, improving contrast and making faint details easier to observe. Amateur astronomers refer to Moon filters as "sunglasses for the Moon" because they provide a more comfortable view and reduce eye fatigue.

This Moon Filter Set contains all the filters you will ever need to observe the Moon during its various phases. The set allows you to choose the best filter to use with different eyepiece and telescope combinations. Use the darkest filter with larger aperture telescopes and lower magnification eyepieces. Use the lighter filters with smaller telescopes and higher magnification eyepieces.

This kit is essential for those looking to take the next step in exploring their telescope's full lunar capability, or for seasoned lunar observers who use a variety of telescopes and eyepieces to observe the Moon.

• Four great Moon filters in one kit-everything you'll ever need for optimal views of the lunar surface
• Three neutral density (ND) filters with different levels of light transmission (13%, 25%, and 50%) allow you to choose the perfect filter for your viewing conditions
• Moon & Sky Glow filter provides high contrast views of the lunar surface and enhances observation of deep sky objects from light polluted skies
• Aluminum filter cells provide a rigid, durable housing for the filter glass and are threaded on top and bottom for stacking
• Kit includes a plastic carrying case with Moon map and legend for identifying the most popular lunar features

In this kit, you will receive:

• Three neutral density (ND) filters: ND96-0.9 13% T, ND96-0.6 25% T, and ND96-0.3 50% T - These filters dim the entire visual spectrum from 400-700nm equally. The ND96-0.9 filter transmits 13% of the incoming light, the ND96-0.6 transmits 25% and the ND96-0.3 transmits 50%. They do not impart any color to the Moon, but reduce lunar brightness. With several ND filters to choose from, you can find just the right level of light transmission for the Moon depending on its phase, the aperture of your telescope, and the magnification of your eyepiece. ND filters can also be used reduce the glare from Venus to better see its crescent phases, and to help dim bright daytime views when using a telescope terrestrially.
• A Moon & Sky Glow filter - This filter selectively reduces light transmission at different wavelengths and greatly improves contrast for observing subtle lunar features. This filter imparts a very light purple color to the Moon. For those in light-polluted skies, the Moon & Sky Glow filter provides some contrast enhancement when viewing deep sky objects due to the filter blocking some wavelengths associated with common forms of light pollution, e.g. low-pressure sodium (LPS) street lights.
• A durable plastic carrying case - The Moon Filter Set comes with a foam-lined plastic case to store all four filters when they are not in use and protect them during transit.
• Moon map and legend - Familiarize yourself with the Moon, our neighboring world with the help of our handheld Moon map. The Moon map comes complete with a legend highlighting 17 key features to explore including Sea of Tranquility, Tycho, Plato, Copernicus and many more.

Housing

Each filter is housed in an aluminum cell, providing a rigid, durable frame for the filter glass. The filters thread onto Celestron 1.25" eyepieces and most other 1.25" eyepieces with a standard filter thread. The filters have threads on the top and bottom to stack with other filters for even more light filtration options.

Explore the Moon

Your Moon Filter Set also includes a free download of Robert Reeves' eBook, Lunar Landscapes, which goes into fascinating detail about the sizes of craters, how marias are formed, the natural history of the Moon, and more.
