Optolong
When it comes to high-performance filters that improve picture quality by increasing contrast and decreasing light pollution, astrophotographers know and trust Optolong. As an exceptional dual-bandpass filter developed for deep-sky imaging of emission nebulae, the Optolong L-Ultimate filter stands out among their offerings. It allows for remarkably detailed and rich pictures, even in extremely light-polluted sky, by accurately separating the H-alpha and OIII wavelengths. With this filter, one-shot color (OSC) cameras can achieve narrowband imaging without using any additional filters, making it an ideal choice for such cameras. It is known for producing clear, high-contrast images while effectively reducing ambient light.

Highlighted Products
Featured Product 1
The Optolong L-Ultimate 2" Light Pollution Dual Band Filter is designed to enhance deep-sky astrophotography by blocking unwanted light pollution while passing key emission lines for nebulae imaging. It combines H-alpha and OIII wavelengths, offering crisp, high-contrast images. Featured in High Point Scientific's "Optolong L-Ultimate Full Review," this filter is praised for improving image quality in urban environments.
Featured Product 2
The Optolong 2" L-Quad Enhance Filter is engineered for astrophotographers looking to capture deep-sky objects with minimal light pollution interference. This multi-bandpass filter isolates H-alpha, H-beta, and OIII wavelengths, improving contrast and color fidelity in images. It allows rich, detailed imaging of nebulae, even in urban environments, by reducing unwanted background light.
Featured Product 3
The Optolong UV-IR Cut 2" Mounted Filter is designed for high-quality astrophotography, effectively blocking ultraviolet and infrared light while allowing visible light to pass. This filter enhances the sharpness and color balance of images by preventing unwanted chromatic aberration. It is ideal for improving image detail and accuracy when using modified cameras or telescopes.
Featured Product 4
Better astrophotography is possible with the help of the Optolong 3nm Filter Kit is 2" mounted H-alpha, SII, and OIII filters, which increase contrast, detail, decrease background noise, and strengthen weak nebula signals. The H-alpha filter blocks atmospheric sky glow and artificial light at 656 nm, the OIII filter improves color reproduction and image structural details at 500 nm, and the SII filter is best for observing nebulae at 672 nm. These coatings make the filters more resistant to scratches and temperature changes, and they also guarantee a high transmission rate and a low optical density, which are necessary for good performance.
Featured Product 5
For astrophotography, the Optolong SHO filter kit includes 36mm unmounted 3nm H-alpha, SII, and OIII filters, which reduce background noise, improve contrast, and bring out subtle nebula signals. To ensure proper alignment with the RGB channels for Hubble image processing, these filters have been fine-tuned for usage with modified DSLRs and monochrome cooled CCD cameras. The filters have an ion-based deposition multi-layer anti-reflection coating and a non-cementing optical substrate. While the OIII filter captures blue-green emissions with a 3nm bandwidth at 500nm, the H-alpha filter captures them with a narrow 3nm bandwidth centered at 656nm. The SII filter's 672 nm center and 3 nm bandwidth make it ideal for nebula observations.
