Premium light-pollution killer!
Celestron's 1.25-inch ultra high-contrast, light pollution reduction (UHC/LPR) filters make deep-sky observation and astrophotography possible in urban areas. That means you can capture stunning views of the Orion Nebula, the Rosette Nebula, the North American Nebula, the Veil Nebula the Helix Nebula, and many, many others from a nearby parking lot!
LPR filters work by reducing transmission of light wavelengths produced by artificial light. This includes mercury-vapor, and both high- and low-pressure sodium-vapor lights. They also block "sky glow," or unwanted natural light, caused by neutral oxygen emission in our atmosphere.
While blocking unwanted light, Celestron LPR Filters permit transmission of more desirable wavelengths, including those of hydrogen alpha, hydrogen beta, doubly ionized oxygen and singly ionized nitrogen.
This will improve viewing of emission nebulae, both from urban and rural areas.
This new, ultra high-contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae is noticeably improved. Advanced-technology coatings enable the filter to achieve outstanding transmission of more than 97 percent across the entire bandpass, with total blockage of prominent light-pollution lines.
Celestron's 1.25-inch UHC/LPR filter is the perfect accessory for viewing nebula from light-polluted skies, or for boosting the contrast of nebula from dark-sky sites. That makes it a must-have accessory for urban stargazers!

Q1: I have a Celestron 127 EQ and live in a light polluted suburb between San Francisco and San Jose. What type of LPR filter do you recommend? What is the difference between an LPR, high contrast, O-III, narrow bandwidth, etc.? Do these all do the same thing? And in what situations are each most effective?
A: All of these filters essentially do the same thing. They will all block out certain band widths and project a high contrast image but there are a few differences. The O-III is the only filter that is recommended for photography because it is made with a thinner glass. The LPR is the only filter you would want to use to battle light pollution because it has additional coatings applied for this purpose that the others don't. For your needs the LPR is the best choice.
Q2: I want to know which filter(s) will be the best one for observing from my area. There is quite a bit of light pollution and a lot of haze towards the horizon. The limiting magnitude is about 9-10 (with a telescope). I want to mainly observe galaxies.
A: Unfortunately, no filter will solve the haze problem; that's air pollution. However, the Celestron UHC/LPR Filter can do something about the light pollution. It's the filter you want for viewing in light-polluted skies.
Q3: Will it fit in my Orion 1.25" eyepieces? Are the threads standard across brands?
A: Yes, the Celestron LPR filter will fit your Orion 1.25-inch eyepieces. The threads are standardized.
Q4: Will the Celestron UHC/LPR Filter - 1.25 Inch fit on the eyepieces in the Zhumell 1.25in. Eyepiece and Filter Kit?
A: Yes, the Celestron UHC/LPR Filter should work just fine with the Zhumell eyepieces.
