FLI Research Grade 65mm Square Ha 8nm Filter



FLI's Research Grade 65mm Square H-Alpha Filter's are of the highest quality, made to the highest standards with the finest production methods. Each and every one is coated in a durable AR coating on both of the filter's surfaces, ensuring that they are highly durable to scratches and dents- with a scratch/dig resistance rating of 60/40. These coatings are of course applied with extreme, exacting precision to make sure they do not impair the filter's performance of their primary intended function. Transmitted wavefront is better than .25 wave/inch at 635nm. Research grade filters are 5 +/- 0.05mm, par focal +/- 0.2mm, (filters start par focal +/- 0.1mm per recipe). Parfocal to f/4.5.

The H-Alpha Narrowband filter transmits only H-Alpha wavelength light, which is found in most nebulae, star clusters, galaxies, and stars. This makes these filters ideal for complex false color imaging of such regions. H-Alpha filters such as this one are excellent for boosting contrast and are most definitely a must have for imaging in areas with high levels of light pollution. This particular H-Alpha filter has a bandwidth of 8nm. Unmounted, this filter will fit into filter wheels made to accept 65mm filters.
