Product Description

The relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. L-eNhance provides an economical and practical solution for amateurs. It is a dual band-pass narrowband filter which has been designed for DSLR (digital SLR), color CMOS and CCD Astrophotography Cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas. Optolong believes the design of our L-eNhance filter is a technical innovation among filters. It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers images that superbly control the impact from light polluted skies. According to the characteristics of celestial body emission lines and the light pollution spectrum, Optolong specially designed and optimized dual-band L-eNhance filter in order to retain the prominent color of nebula RGB while blocking out most of light pollution. The Optolong L-eNhance filters have threads on one side - they can be used with filter wheels, filter drawers, focusers with a place to thread focal reducers internally (such as some Moonlite focusers) and camera nose pieces that fit into compression rings but the filter should not be threaded into the imaging train like an adapter ring with threads on both sides. Substrate: B270 Thickness: 1.85mm Tpeak: T>90% Blocking range: 300-1000nm Blocking depth: Light pollution line blocking >99% Surface quality: 60/40 Transmitted Wavefront RMS: λ/4 Parallelism (arcsec): 30s

5.0 out of 5 stars The moon doesn't scare me anymore
Reviewed in the United States on December 4, 2019
Verified Purchase
This thing is incredible. Now, even if there's a full moon, I can be outside imaging. So it's effectively multiplied my imaging sessions many times over. I use it on a Skywatcher ED80 with an asi294mc camera. Before I got this filter, I would just shut everything down when the moon was bright, which was a shame because those always seemed to be the clearest nights also. But with this filter, the moon doesn't even seem to exist. The filter really shines on emission nebula, which I guess is what it's really designed for. I've taken tremendous photos of the N. America nebula, the Heart nebula, the Wizard, etc., again, even with a full moon. I also use it to supplement my galaxy photos. I don't really know what I'm doing in that regard, but I find combining frames with and without the filter really enhances my galaxies (especially the Triangulum.) Other than buying a better mount (eq6-r pro), this is hands-down the best astrophotography purchase I've ever made.

5.0 out of 5 stars Excelente filtro para fotos de nebulosas de emisión!
Reviewed in Mexico on February 6, 2022
Verified Purchase
Como dice el titulo, un excelente filtro que separa muy bien las ondas de luz de hidrógeno alfa y beta y O III. Me permite tomar fotos de nebulosas de emisión desde mi casa en la ciudad (Bortle 7). El precio es adecuado para la calidad y lo que ofrece el filtro. Además llegó muy rápido.
Nota: este filtro está diseñado mas para astro fotografía con cámaras DSLR y cámaras dedicadas a astro fotografía a color no para visual en el telescopio, así que no esperen ver mejor usando este filtro desde cielos con contaminación lumínica.
Otro punto importante a considerar es que sirve para nebulosas de emisión, las galaxias y nebulosas de reflexión no se benefician con su uso o lo hacen muy poco.
Revisen un poco en internet para comprender mejor su uso antes de hacer la compra.
Por cierto, también existe el filtro L- extreme que es mejor en muchos aspectos pero también tiene un costo mucho más elevado.
