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. You can use it 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 a distance from the camera to the bottom of the smartphone of up to 160 mm. The secure 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 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.

3. 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 respective camera is needed.

4. Celestron Power tank 12V 3AH Li-Iron
This mobile power supply offers versatile applications: 12V/3A including connection cable for the telescope connection, a 5V/2.1A charging port for tablets, and a 5V/1A charging port for smartphones. It also features a flashlight function with optional red or white light and a strap for attaching to a tripod leg. The power tank has a robust housing that is dust and waterproof. The lithium iron phosphate battery offers significant advantages: high storage capacity, as the battery is not damaged even after long periods of non-use (up to ten years). Each battery loses its performance with each charge cycle, but this decline occurs much more slowly with the LiFePO4 battery, lasting up to 2000 charge cycles. The charging time is a maximum of 3 hours. The power tank is environmentally friendly, as it contains no toxic heavy metals, is explosion-proof, and has no memory effect. This power tank will last as long as your telescope. The best part: we provide this power tank with a special angled plug. If the power cable gets tangled around the mount during an observation night, only the plug is disconnected, preventing damage to the mount's socket. It's often the small details that matter in astronomy accessories.

5. Celestron StarSense module
With azimutally mounted telescopes, StarSense allows alignment without GPS, without entering coordinates, without aligning and leveling it to the north and without cumbersome approaching of stars. The StarSense module also brings great advantages when combined with parallactic mounts. Although pole adjustment is still required, with the new "AllStar" process from Celestron this is done on every star within a few minutes. Simply enter the location and time, select the star from the database and move it to the center of the crosshair with azimuth and height adjustment. Ready. StarSense can then use the fully automatic "3-minute plate solving process" to provide exact orientation without any further user input, just as it can with azimuthal mounts. The cumbersome, lengthy starting and centering of guide stars is no longer necessary. Another advantage of the StarSense is the extreme improvement of positioning accuracy via the T-Point method. Similar to some high-end mounts, any number of stars can be "mapped", i.e. approached, positioned exactly in the middle of the crosshairs and the exact position confirmed by "Enter". From ten mapped stars (which should be distributed over the entire visible part of the sky if possible) the positioning accuracy becomes extreme. The secret of the StarSense technology is a small camera module which is placed on the telescope like a viewfinder. It takes 3 wide-angle photos of different areas of the starry sky, the StarSense hand controller analyzes these photos and calculates the position of the other objects of the starry sky. The StarSense module comes with the StarSense hand controller.

6. Celestron Moon Filter Kit 4 pcs. 1.25
Three ND filters 0.3 / 50%, 0.6 / 25% and 0.9 / 13% and a Moon & Sky Glow filter allow you to choose the perfect filter for your viewing conditions. The Sky Glow filter provides a high contrast view of the lunar surface and improves observation of deep sky objects in light polluted skies. Includes case and moon map. The Moon & Sky Glow Filter selectively reduces light transmission at different wavelengths and greatly improves contrast for observing the moon. This filter gives the moon a very bright purple color. In light polluted skies, the Moon & Sky Glow Filter provides some contrast enhancement when viewing deep sky objects, as the filter blocks some wavelengths associated with common forms of light pollution, such as low pressure sodium street lamps.
