Celestron UHC/LPR 1.25" Light Pollution Fi... $134.95
Our 1.25" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapour, and both high and low pressure sodium vapour lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). Description The ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire...

Celestron Variable Polarizing Filter 1.25"... $53.95
When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be reduced to just 1% or as much as 40%. To make the adjustment, simply rotate the filter’s lower ring and the image gets brighter or dimmer. Description This filter does not alter the colour of the object you’re observing, making it a great choice for astroimaging, especially when imaging the surface of the Moon. By reducing the brightness, lunar details become more pronounced...
