Multi-Band fitlers
Discover the power of Optolong's multiband filters—L-eNhance, L-eXtreme, and L-Ultimate—designed to elevate your astrophotography by effectively combating light pollution and enhancing nebular detail.
Optolong L-eNhance Filter
The L-eNhance is a tri-bandpass filter that transmits H-alpha, H-beta, and OIII wavelengths. Its broader bandpasses make it ideal for capturing emission nebulae with a more natural color balance, especially when using DSLR or color CMOS cameras. This filter excels in moderately light-polluted skies, offering a cost-effective solution for astrophotographers seeking to enhance their deep-sky images.
Optolong L-eXtreme Filter
The L-eXtreme is a dual-bandpass filter that isolates H-alpha and OIII emissions with 7nm bandwidths. This narrowband design significantly reduces light pollution, making it perfect for imaging emission nebulae from urban areas. While it offers higher contrast and better signal-to-noise ratios than the L-eNhance, users should be aware of potential star halos around bright stars.
Optolong L-Ultimate Filter
The L-Ultimate stands out with its ultra-narrow 3nm dual-bandpass, targeting H-alpha and OIII lines. This filter provides superior light pollution suppression and minimizes star halos, delivering high-contrast, clean images of emission nebulae. It's especially beneficial for astrophotographers operating in heavily light-polluted environments and seeking the highest image quality.
Each of these Optolong filters offers unique advantages tailored to different astrophotography needs. Whether you're capturing the vibrant colors of nebulae with the L-eNhance, seeking higher contrast with the L-eXtreme, or aiming for the utmost clarity with the L-Ultimate, Optolong has a solution to enhance your deep-sky imaging experience.
