Optolong Filter H-Alpha 7nm 2 This premium Optolong Narrowband H-Alpha filter is designed for nebula observation or CCD/dSLR imaging at 7nm bandwidth of light centered on a wavelength of 656nm, which corresponds to H-alpha emission lines. I did not hear good things about the 12nm h-alpha filters, especially if you are going to be using them for DSLR imaging, from all the googling and reading I did about h-alpha imaging with a DSLR you want to stick with 7nm or narrower h-alpha filter to generate the most contrast. The Optolong 2” H-Alpha 7nm Filter is made with Schott glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength, or CWL. The filter cell is made of lightweight, strong metal and is CNC machined, sand-blasted, black anodized, and then laser engraved. The result is a super thin filter cell that will produce a clear aperture of 45mm. OPTOLONG H-ALPHA 7NM FILTER H-Alpha 7nm filter is the most popular narrowband filter allowing 7nm bandwidth of light centered on a wavelength of 656nm through, and AstroBin is an image hosting website specifically targeted to astrophotographers: it's the first and the last place where you need to upload your astrophotography images. Made by an astrophotographer, for the astrophotographers.
