Astromania 2" Narrowband H-alpha 12nm Astrophotography Filter for Telescopes, Metal

The Astromania 2" Narrowband H-alpha 12nm Filter is designed for astrophotography, especially under light-polluted skies. This specialized filter helps enhance the contrast between celestial objects and the sky, allowing for high-quality images even in urban environments. It effectively blocks a significant portion of light pollution, including stray light from artificial mercury and sodium-vapor lamps.

Key Features:
* Filters out light pollution for clearer astrophotography results.
* Allows a 12nm bandwidth of light centered on the H-alpha line (656nm) to pass through, with 90% transmission.
* Ideal for capturing hydrogen nebulae, revealing embedded young stars in stunning detail.
* Enhances contrast between celestial objects and the night sky.
* Features a durable metal filter cell that threads directly into any 2-inch telescope eyepiece.
* Mounted in a nicely anodized housing for long-lasting performance.
