[sold] 2" Threaded Thousand Oaks H-Beta Filter, Reduced
Upgrading my filters to a full set that fits my STL Camera (50mm unmounted) that are also Par-focal. These filters (and the Broadband posted) are in A1 Condition, always kept in their packets. They are about 8 Months Old.

Enhance your deep sky viewing with the latest in multi-layer coating technology. Thousand Oaks H-Beta Filters transmit desired wave-lengths in a very steep slope vs. gentle transition slopes in competitive brands. Thousand Oaks Hydrogren-Beta filters give you better contrast and overall performance.

H-Beta filters are designed for a narrow hydrogen-beta wavelength and work well for objects such as the "Horsehead" nebula.
