If you’re looking for a way to really add some bang to your emission nebula, then hydrogen alpha data is probably the way to go. To that end we have this offering from Astronomik. A 12nm hydrogen alpha filter that can clip into a DSLR camera body. Isolating a singular wavelength of light – 656nm – and then letting the sensor capture that can really make a difference in your astrophotography. Taking your images all the way up to 11.
There are several reasons why to invest in a hydrogen alpha filter, there are also a lot of filters out there to choose from at different wavelengths. But for now, in this article, I’m going to talk about my findings having used the Astronomik 12nm Ha filter which was on loan from The Widescreen Centre.
