Optolong L1 Dual-Combo Set 2" - L-Quad Encance and L-Para Narrowband Filter

Optolong L1 Dual Combo Set 2"

The set is an optimal combination of broadband and narrowband filters for high contrast and color fidelity in astrophotography. The set is very well suited for color cameras, but can also be used for monochrome cameras. While the L-Quad broadband nebula filter captures the entire RGB signal of celestial objects and ensures natural colors, the L-Para narrowband nebula filter captures the finest structures and ensures high contrast. The combination provides more vivid and natural color reproduction and shows the finest details.

L-Quad Enhance Filter:Quad bandpass broadband filter. This filter provides better color balance while improving resistance of light pollution. It is suitable for a wide range of imaging targets, including continuous spectrum objects (RGB) such as nebulae, galaxies, and star clusters. This filter maximizes the preservation of RGB color balance in broadband spectrum targets like nebulae and galaxies, effectively improving contrast and detail to render subjects more vivid and three-dimensional.

L-Para:A dual narrowband 10 nm filter. In systems with a focal ratio of f/2 and above, the transmittance of nebula emission lines [O III] and H-alpha exceed 85%, with excellent contrast and Anti-Halo characteristics. This filter suitable for all telescope systems, adaptable to fast optics (focal ratios of f/2, f/2.8, f/3.2, f/4) as well as various standard/normal focal ratio telescopes. Ideal for capturing H-alpha & [O III] signals in celestial objects, this filter enhances image contrast and reveals richer details in -alpha & [O III] emissions.
