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.

2. Celestron Basic Smartphone Adapter
Capture your observations with this practical, easy-to-use smartphone adapter and share them through nearly any optical device. Whether you want to take an Instagram-worthy picture of the moon, share your latest wildlife observations with binoculars or a spotting scope, or capture lab samples with your microscope, this versatile adapter handles it all effortlessly.
Installing and using the adapter is straightforward. First, place your phone in the adapter. It is securely held in position by the locking buttons that fix your phone in place. Align the phone's camera with the center of the eyepiece. Once you find the perfect position, clamp the adapter over the eyepiece and use the buttons to adjust for a secure fit. Note: Some large and/or bulky phone cases (including folio-style cases) may need to be removed for the phone to fit into the adapter.
Once the phone is mounted over the eyepiece, you can take still images or videos and access all other functions of your phone. You can even send your photos to a friend or post them on social media while your phone remains mounted in the adapter.
To determine if your optical device is compatible with the Basic Smartphone Adapter, simply measure the outer diameter of your eyepiece. If it falls within the range of 29 mm to 45 mm, you can use it with this adapter. The adapter does not work with riflescopes.

3. Celestron Mondfilter
The moon has the distinction of being the most viewed celestial object through backyard telescopes. It is undoubtedly beautiful and mysterious, and it is one of the constants in life that connects all people on the planet. Regardless of who they are or where they live or travel, they all look up at the same moon. It can be challenging to observe the moon through a telescope and to discern all the details due to its brightness. The eyes are not prepared for the bright beam of light emitted from the eyepiece, and they become dazzled, just as they would when stepping into sunlight on a bright summer day. When they are in the sun, they often wear sunglasses. These help relax the eyes, protect against glare, and allow for clearer vision. Amateur astronomers observing the moon use a moon filter. A Celestron moon filter offers similar benefits to sunglasses – one eye relaxes and opens up to better perceive the details. This is especially important when the moon is near full. The Celestron moon filter easily screws onto the eyepiece of most 1.25-inch eyepieces. It takes just a second or two to transform a regular eyepiece into one suitable for moon observations. A moon filter is also helpful when observing Venus or bright terrestrial scenes. However, this filter is not suitable for viewing the sun.

4. Vaonis CLS Filter for Vespera
Vaonis CLS Filter for Vespera
With the Vespera light pollution filter or CLS filter (City Light Suppression), you can enhance the quality of your photos when observing in urban or suburban areas. It reduces the effects of light pollution, thereby increasing the contrast between the photographed celestial object and the background sky. Essential for observing from a location with high light pollution.
The filter improves the quality of nebula photography. The broadband filter blocks wavelengths from sodium and mercury, which are primarily emitted by urban night lighting or unwanted natural light, while allowing the main wavelengths of celestial objects to pass through. The light pollution filter is particularly useful for enhancing the brightness of deep-sky objects such as nebulae, star clusters, and galaxies. Due to the filtered wavelengths, it is especially effective for emission nebulae.
Features:
- CLS Filter for Vespera (AC023)
- Transparent storage box
- Dimensions: Depth: 0.6 cm, Width: 7.80 cm
- Color: Black (outside)
- Materials: Glass, Plastic
- Weight: approx. 15 g.

5. Vaonis Dual Band Filter for Vespera
Vaonis Dual Band Filter for Vespera
The Vespera Dual Band Filter is a narrowband interference filter that significantly enhances the quality of your images, whether you are photographing in the city or in nature. By precisely selecting the wavelengths of Hydrogen Alpha (H-Alpha) and Oxygen III (O-III), which are primarily found in nebulae, the filter increases the contrast between the star object and the sky background. This results in better image quality with sharper stars and finer details.
Features:
- Improves photo quality
- Ideal for nebula photography
- Increases contrast between the sky background and the star object
- Refines stars and details
- The dual band filter only allows two specific wavelengths to pass through to the Vespera sensor: O-III and H-Alpha
- Usable at full aperture
- The lens ring is equipped with an electronic microchip that allows Vespera to recognize the dual band filter and adjust its observation and image processing parameters
- The filter has a bandwidth of 12 nm at each wavelength (O-III = 500.7 nm, H-Alpha = 656.3 nm)
- Compatible with Vaonis Vespera.

6. Celestron Accessories kit Astromaster
The AstroMaster accessory kit is the perfect complement to the AstroMaster telescopes. It provides additional magnifications and filters to better observe details on the planets. You can also use it with any other telescope that has a 1.25" eyepiece holder. Enjoy your telescope even more with the Celestron AstroMaster accessory kit. In the plastic carrying case lined with foam, you will find the following accessories: 15 mm Kellner eyepiece - 1.25"; 6 mm Plossl eyepiece - 1.25"; 2X Barlow lens with T-thread - 1.25"; 80A blue filter - 1.25"; red filter - 1.25"; moon filter - 1.25"; microfiber cleaning cloth.

7. Explore Scientific Solarix solar filter foil A4

9. Celestron T-Ring Canon EOS
This Celestron T-Ring attaches to Canon EOS DSLR and SLR camera bodies. The sturdy bayonet flange locks in place just like a lens, providing secure contact. It attaches to a variety of camera adapters and accessories via standard T-threads. This T-ring fits EOS model cameras only and will not work with other Canon camera bodies.
A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you.
To use the Canon EOS T-Ring, remove the lens from your camera and attach the T-ring in its place, just as you would if you were mounting a lens. The telescope side of the T-ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do.
You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor, the Universal T-Adapter (#93625), with its 1-1/4 inch barrel insert, is available. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646).
Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.
If you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.
