1. 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.

3. 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. 

4. Celestron RA motor control

Add this motorized mount to your AstroMaster or PowerSeeker telescope (Celestron CG-2 or CG-3 mount), and you can start tracking stars. This easy-to-install motorized mount compensates for Earth's rotation, allowing the telescope to follow the movement of stars from east to west. Once the RA mount is installed and powered on, you only need to make minor adjustments, and you can track the same object for an extended period. 

5. Celestron T-Adapter Universal

Universal T-Adapter - 1.25 inches

With these Celestron T-adapters, 35 mm SLR cameras can be connected to the primary focus of a telescope or spotting scope. The
adapter is inserted and secured in place of the eyepiece in the 1.25-inch eyepiece holder. This allows you to take terrestrial photographs as well as images of the Moon and planets. For deep sky photography, an additional guide scope is required. In addition to the T-adapters, a T-ring specific to the camera is also needed. 

6. Celestron T-Ring Nikon

The Celestron T-Ring 93402 for Nikon cameras allows for the direct connection of Nikon SLR and DSLR cameras to telescopes or spotting scopes for astrophotography and nature photography. The adapter replaces the camera lens and provides a stable connection to T-adapters and other T2 accessories.

The robust bayonet mount securely locks onto the camera like a standard lens, ensuring a reliable connection during shooting. Thanks to the standardized T-thread, the T-Ring is compatible with numerous T-adapters, tele-extenders, and astrophotography accessories.

- Suitable for Nikon SLR and DSLR cameras
- Direct connection to telescopes and spotting scopes
- Standard T2 thread for versatile compatibility
- Compatible with Celestron T-adapters and tele-extenders
- Ideal for astrophotography and nature photography
- Robust bayonet mount for secure hold
- Easy installation in place of the camera lens
- Black anodized aluminum construction
- Interior surfaces are blackened to reduce reflections
- Suitable for moon, planet, and deep-sky photography

The Celestron T-Ring is perfect for amateur astronomers and photographers who want to use their Nikon camera for high-quality shots through a telescope.
 

7. 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.

8. Celestron 45-degree amiciprism 1 1/4

1 1/4" Amici. For earth observations. Displays a correctly oriented and upright image (not suitable for Newtonian optics). Zenith prisms are the most important accessory for refractors and Schmidt-Cassegrain or Maksutov reflecting telescopes after the eyepieces. They are needed for a more comfortable view during zenith observations and for image inversion. 

9. Celestron simple zenith mirror 1 1/4

After eyepieces, zenith prisms are the most important accessories for refractors and Schmidt-Cassegrain or Maksutov reflecting telescopes. They are needed for a more comfortable viewing during zenith observations or for image inversion. On Newtonian reflectors, these accessories cannot be used for optical reasons - and do not need to be, since the optical path in the Newtonian telescope makes this unnecessary. This zenith prism provides an upright, side-swapped image. All Celestron zenith prisms have a high quality coating. 

10. Celestron 18775 USB to RS-232 Converter Cable

The Celestron USB-to-RS-232 Converter Cable enables a seamless connection between older serial Celestron telescope cables and modern computers or laptops via a USB port.
