Enhance your deep sky viewing with the latest in multi-layer coating technology in filters from Thousand Oaks Optical. Their filters transmit desired wave-lengths in a very steep slope vs. gentle transition slopes in competitive brands. This means better contrast and overall performance.
The H-Beta filter is well suited for use on objects such as the Horsehead, California nebula, and other faint nebulae.

H-Beta filter 2"Pros: Cons: Comments:
A beautifully machined filter, free of faults, will complete my collection of visual filters for deep-sky observation. Unfortunately, clear skies have yet to come.
