1.25" Orion UltraBlock NarrowBand Filter
The 1.25" Orion UltraBlock Narrowband telescope eyepiece filter is the filter of choice for deep-sky observers viewing from highly light-polluted sites.

Light pollution can significantly decrease the quality of telescopic views of deep-sky objects. The UltraBlock filter blocks all forms of light pollution from incandescent and fluorescent lighting, including mercury vapor and sodium emission bands, while passing critical hydrogen-beta and ionized oxygen wavelengths.

I haven’t used this filter for a while as I have moved to Astrophotography with narrowband filters.
Price: £45
