1. Celestron NexYZ 3 axis
The NexYZ Universal 3-Axis Smartphone Adapter for Digiscoping fits all eyepieces with a diameter of 35 mm to 60 mm without the need for an adapter. It can be used with telescopes featuring 1.25" and 2" eyepieces, as well as with spotting scopes, monoculars, and binoculars. With the two included adapter rings, you can also use NexYZ on slimmer (microscope) eyepieces down to 25 mm in diameter. A strong spring and a threaded locking mechanism ensure a secure grip on the eyepiece of the optical instrument, keeping the smartphone safe. The NexYZ is compatible with a wide range of smartphones up to 92 mm in width. It can be adjusted to fit any device, typically even when the smartphone is in a protective case. Even large "phablets" like the iPhone 8 Plus and the latest Samsung Galaxy devices work perfectly, with the distance from the camera to the bottom of the smartphone being up to 160 mm. The sturdy platform easily supports the weight of these heavy devices. If multiple people want to take photos through your optics, you can quickly swap one device for another thanks to the spring clamp. NexYZ is the ideal solution for star parties or group birdwatching, where everyone wants their own picture of the action.
Pro
- X/Y/Z axis adjustable
- Solid construction
- Even more adjustable thanks to X and Y axis
Contra
- Relatively heavy (on the telescope)
- can influence the balance of the telescope with 288 grammes of weight.

2. Celestron Red. lens 0.7x f. 800 Edge
Reducer for 800 Edge-HD
The EdgeHD Reducer features optics specifically calculated for EdgeHD telescopes, consisting of five optical elements, including lanthanum glass, while maintaining the flat image field of EdgeHD optics. Unlike simpler reducers designed for APS format, the Edge-HD Reducer does not shorten the original backfocus of 146 mm. This allows for the connection of any DSLR camera, as well as all known CCD cameras with filter wheels and active optical systems, as well as off-axis guiding adapters.
The 0.7x EdgeHD Reducers include lenses with an extremely high refractive index, including lanthanum lenses with very low dispersion. This ensures that the particularly high contrast of the Edge-HD optics remains uncompromised despite the many additional lenses, and no chromatic aberrations occur over a very wide spectral range. Each glass-air surface in this lens system is multi-coated to maintain maximum transmission and color fidelity. All lens edges are carefully blackened to completely suppress internal reflections.
The large lenses, with diameters of up to 60 mm, allow for a fully illuminated image circle with a diameter of 42 mm, suitable for large CCD sensors. The intricately CNC-machined aluminum housing ensures precise spacing and accurate alignment of the lenses. Metal screw caps protect the lenses from dust and damage when the Edge-HD Reducer is not in use. Together with the f/2 HyperStar option and the f/7 Edge-HD Reducer, the f/10 Celestron EdgeHD Schmidt-Cassegrain optics become the most versatile telescope optics in their price range. It allows the use of existing EdgeHD T-adapters with or without the Edge-HD Reducer.

3. Celestron LensPen Pure Brush
How often has dust or lint ruined an observation session on your eyepiece or telescope? A seemingly harmless strand of hair scattered across your photos or astrophotography can require hours of cleaning in an image editing program, and a greasy fingerprint or smudge on the optics can cause an otherwise perfect image to end up in the trash. This is where the Celestron LensPen comes in, an optical cleaning device with dual functionality that is small and lightweight enough to fit in your telescope accessory bag or camera bag, ensuring it’s always on hand when you need it. The LensPen is two cleaning tools in one. One end features a soft brush for removing dust and other particles from any optical surface. The other end of the LensPen addresses smudges that cannot be wiped away. This device has a special cleaning tip that works without liquids, so it never dries out. A cap protects the smudge-removing tool when not in use, while the brush is safely stored inside the LensPen. When cleaning optics, it’s always best to start with the brush, even if you think it’s unnecessary. Carefully brush the entire surface and then check your work. If you spot streaks or smudges, remove them with the cleaning element by gently touching the surface. The Celestron LensPen is a fantastic tool for all your optical equipment, including eyepieces, telescopes, spotting scopes, binoculars, microscopes, cameras, lenses, and more.

5. Celestron SkyPortal WiFi Adapter
The new SkyPortal Wi-Fi module (formerly known as SkyQ Link) enables wireless control of almost any Celestron GoTo telescope with the optionally available "SkyPortal" app, available for both iOS and Android. In this app, a complete planetarium program, you can simply tap on an observation target on the star map or in a list, and the telescope will automatically move to it. The telescope can also be operated via SkyPortal without a hand controller, and even the alignment is possible through SkyPortal.
