This filter set provides an affordable alternative to the more expensive filter sets offered by other manufacturers. Despite the lower price, these are high-quality, multi-coated interference filters. The set is specially optimized for use with ZW Optical’s ASI cameras. By combining exposures from the three color filters (red, green, blue) and the luminance filter (which also acts as an IR cut filter), you can create full-color images on your computer.

The ZWO Duo-Band Filter is a dual narrowband filter designed especially for use with color ASI cameras. It is ideal for astronomers who already own a color camera and want to try narrowband imaging or capture emission nebulae, without needing to buy a monochrome camera, filter wheel, and multiple narrowband filters. This filter provides an affordable way to explore narrowband imaging and is also a practical solution for astrophotography in light-polluted urban environments.

The ZWO M54 filter holder is a highly advanced filter drawer designed with many useful features, making it an excellent alternative to bulky and heavy filter wheels. Astrophotographers who prefer a compact and lightweight setup will appreciate this filter drawer, which maintains both stability and accuracy despite its small size. This filter drawer is specifically developed for use with full-frame cameras such as the ASI6200MM and ASI6200MC Pro, but it is also compatible with other cameras featuring an M54x0.75 connection.

This filter drawer is an excellent option for astrophotographers who want to avoid using a large and sometimes heavy filter wheel. Its compact and lightweight design does not compromise on stability or accuracy, making it both practical and reliable.

This filter drawer is designed by ZWO specifically for use with Nikon F lenses and cooled ASI cameras that have a 17.5 mm working distance. With this accessory, you can attach your Nikon lens for astrophotography and use 2" filters to enhance contrast, or for L-RGB and narrowband imaging.

The ZWO AM3 is a highly portable harmonic equatorial mount designed for astrophotography. Weighing less than 4 kg, this mount can support telescopes up to 8 kg without the need for counterweights. With an additional counterweight and rod (not included), the capacity increases to 13 kg. Years of development and multiple patents have contributed to the advanced design of this mount. The AM3 can function in either equatorial or azimuth mode. Equatorial mode is ideal for astrophotography and requires precise alignment with the celestial pole.

This transmitted light spectroscope is a simple yet precise instrument designed for observing and analyzing the spectra of various light sources. It features a tube with a precision entrance slit and a 600 lines-per-millimetre grating, allowing users to easily point it at different light sources such as the sky (to observe the solar spectrum and Fraunhofer absorption lines), flames for chemical analysis, liquids for their absorption spectra, or the bright lines from discharge tubes and lamps.

This compact spectroscope features a high-performance flat-field concave grating in a module measuring just 136 x 120 x 75 mm and weighing 1.2 kg. It includes a built-in Lodestar X2 guide camera and an argon-neon calibration lamp for precise wavelength calibration. Both the input and output are equipped with T2 threads, making the unit compatible with most imaging cameras that use T2 thread connections. Starlight Xpress recommends pairing this spectroscope with the Trius SX-694 camera for optimal performance.
