1. 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 during observations 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 environments with high light pollution (urban and suburban settings, residential lighting, etc.).
The filter improves the quality of nebula photography. The broadband filter blocks wavelengths of sodium (Na) and mercury (Hg), 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.

2. Baader Planetarium Neodymium filter 1¼
Neodymium moon and skyglow filter with integrated IR blocker and PG coating. The best visual and photographic filter for enhancing contrast for all telescopes, without loss of image brightness. The effect of neodymium as a filter material is very impressive. When added to optical glass, it enhances contrasts, increases the red color component in images (especially with Mars and Jupiter), and simultaneously darkens the spectral range that suffers most under streetlight, which is primarily responsible for night skyglow. Planoptically polished and multi-coated; can be used as a standalone filter in front of binoculars or for afocal projection with digital cameras (well before the focal point) without any loss of sharpness. When used with DSLR cameras, stars are rendered significantly sharper because the IR spectral range is blocked.

3. 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.

9. 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:
- Enhances 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 enables 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.

10. 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.
