For filter wheels that accept 36mm.

Compact versatile 60mm aperture guide scope with a built-in helical focuser for precise of potential guide stars.

SV182 with 6x power magnification and a 30mm diameter lens collects ample light to make aiming your telescope easy and fun.

Designed specifically for SV503 70mm, 80mm, and 102mm f/7 ED Refractor.

Will be in stock in September.

Svbony SV106 50mm finder achromatic refractor with helical focuser. SV106 has FMC (fully- multi-coated) green coating, which can enhance the light transmittance and accurately track the celestial body being photographed.

When total solar or partial eclipse happening, it can greatly shorten the searching time using this solar finder scope, you can observe the real-time location of it when the sun moving.

Versatile 60mm aperture Guide Scope with a built-in helical focuser for precise focusing of potential guide stars. Svbony SV106 Guide Scope can ensure that the main mirror accurately tracks the celestial body to be observed. This SV106 is used as a deluxe straight-through finder scope with optional 1.25" eyepieces installed (eyepieces sold separately)

The H-Beta filter is a narrowband filter specially designed for visual observation like Horsehead Nebula California and Cocoon Nebulae in Dark Skies.

SVBONY SV184 Red Dot Finder Scope for Astronomy Telescope, SV184 Sight Scope for targeting and hunting.

The SHO filter is highly transparent, allowing the emission spectrum of the nebula to collect as much energy as possible by accumulating exposure.
There is higher contrast and the level of the nebula is richer and more delicate.

When the focal length of the telescope is too long to observe a large area of celestial body with low magnification (such as the moon), you can connect the telescope with a focal reducer, shorten the focal length first, and then use a low magnification lens to observe.

The 1.25'' H-Beta 25nm Filter allows you to visually observe the ever-popular yet elusive Horsehead Nebula with large aperture telescopes under dark skies, and can also be used to image the Horsehead as well as others that emit light at 486nm, such as the California and Cocoon nebula.

The SVBONY 2" SII Filters are made of glass import from Germany that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength or CWL.

Narrowband OIII filter is designed for nebula observation allowing 18nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.

SVBONY SV139 Neutral Density(ND) filter is suitable for 1.25-inch eyepiece. The filter can reduce the overall brightness of the moon's surface.  so you can see more details and surface features of moon with your telescope.

Svbony UV/IR Cut Filters compatible with DSLR cameras, CCD cameras, Astronomy Telescopes. High-quality, very latest coating technology optical glass to block UV/IR light. Provides the best color balance and sharpness.

Dark Filter would be used in a filter wheel for CCDs without a mechanical shutter to make dark frames. This handy 1.25'' filter ensures your acquired dark frames will be completely free of unwanted stray light and reflections for great results.

Svbony Oxygen III 7nm extra narrowband filter transmits a 7nm bandwidth of light that is centered at 500nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution(both artificial and natural).

Because Svbony Brand H-Alpha Filter is 656nm mainly through the high permeability of the spectrum, and 656nm spectrum of the color presented by the red-based, 300-1100nm cut-off depth to get the details of the launch nebula richer.

The combination of the Moon filter and the CPL filter and the five color filter sets provide you with the details of the moon and the planet, as well as different color experiences. A nice beginner's set of planetary filters for any 1.25'' telescopes.

The Svbony SV183 IR Pass 685nm filter blocks wavelengths below 670nm to enhance contrast and surface detail and reduce the effects of seeing when used in IR-LRGB imaging of the moon and planets.

Reduce glare and increase contrast of the moon with the Svbony moon filters. Also useful for extra bright planets as well as terrestrial viewing over sand or snow.This filter is not suitable for viewing the Sun. We provide you with two sizes to choose from, 1.25'' and 2'', please choose one size that suitable for your focuser.

The SVBONY Filter is suitable for 2 inch eyepieces and for viewing with single-lens reflex camera and CCD camera (M48 to M42 adapter exclude). Filters can be replaced very quickly, even when the camera is installed or the eyepiece is inserted.
