Optolong NK-Z clip filters are not compatible with all Nikon Z-mount cameras. Please verify compatibility with your specific camera model before purchasing. This filter is designed to enhance the contrast of deep-sky objects while reducing the brightness of the sky background. It works through a sophisticated transmission profile that allows important emission lines from deep-sky objects to pass through while suppressing common sources of light pollution. It also reduces unwanted sky background caused by atmospheric oxygen emissions, often referred to as "skyglow."

The L-Synergy is a dual 7 nm narrowband filter designed for use with DSLR cameras, color CMOS sensors, and CCD cameras. It is compatible with telescope systems that have an f-ratio of f/3.3 or slower. Its main advantage is that it allows astrophotography enthusiasts to capture highly detailed images of emission nebulae, even in areas affected by significant light pollution.

Tax included
The L2 Dual-Combo Set includes two 7 nm narrowband filters designed for astrophotography. These filters are suitable for use with one-shot color cameras such as DSLRs, as well as monochrome CCD and color CMOS cameras. They are particularly well suited for fast optical systems and also support telescope systems with an f-ratio of f/3.3 or slower. One of the filters in this set isolates the H-alpha and Oxygen III emission lines, maximizing contrast and improving the signal-to-noise ratio when imaging nebulae.

The LRGB filter set is designed for color astrophotography using monochrome CCD cameras. It includes four filters that work together to produce a full-color image of deep-sky objects while maintaining the high resolution that monochrome sensors provide. Monochrome CCD cameras are preferred in astrophotography because every pixel on the sensor contributes to capturing image detail. In contrast, color CCD cameras reduce effective resolution since approximately one third of the pixels are covered by built-in color filters.

Sharpstar Reducer 0.75x (87704)
Sharpstar Reducer 0.75x (87704)

This focal reducer shortens the effective focal length of the telescope, making the optical system faster for astrophotography. As a result, images appear brighter and the field of view is increased. By concentrating more light onto the camera sensor within the same exposure time, the reducer improves the signal-to-noise ratio.
