Product description Improve your views of deep-sky objects like galaxies and nebulae, while virtually eliminating the interference from ground-based light pollution with the Levenhuk Ra H-Beta Nebula/Light Pollution Eyepiece Filter. With a bandbass between 4720 to 4850Å, the filter passes the Hydrogen-Beta (H-beta) emission line at 472-485 nm, helping to brighten dim or gaseous-appearing phenomena such as nebulae and improving the contrast for better viewing; while suppressing up to 90% of artificial light coming from street lights, homes, cars, and other sources to make the sky appear darker. This filter can be used for astrophotography applications, and is designed to simply thread onto most 1.25" barrel diameter eyepieces.
