I have the 2" version for my serious astrorigs. But I got a unistellar evscope2 and figured this would be a good upgrade for it.

This filter is awesome!!! I took the attached images from my bortle 6 light polluted driveway. I used a Skywatcher Evoguide 50ED scope, Starizona field flattener, ZWO ASI 585MC camera, Skywatcher Star Adventurer GTI mount and the Optolong l Enhance filter.

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.

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.
