Description

Premium light-pollution killer!

 


Celestron's 2-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!

 

Advanced Technology
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 2-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!

        Comments about Celestron Telescope UHC/LPR Filter - 2 Inch:

        The Celestron filter did out preform my Meade broadband filter. It's not a true UHC filter but did make some objects stand out more than a standard LP filter.

                  Comments about Celestron Telescope UHC/LPR Filter - 2 Inch:

                  You want to know about light pollution? I live in Los Angeles, and we've got it. I bought the 2" filter thinking it might be a cure-all for LP. Not so much, for this reason: UHC filters darken most of the objects you'll be looking at also. For photography, where longer exposures come into play, it's definitely helpful. For casual observing, it's not quite as helpful depending on the type of object you're viewing. I've had great success with this filter viewing a few nebulae and planets, as it makes certain details more noticeable for sure.
                  Pros: It makes the background sky darker; enhances details on some objects.
                  Cons: Also dims whatever else you view; imparts a blue-violet cast.
                  For a change of perspective, it's great to slap on a filter and see what you might be missing. I'm glad I bought it, but wonder if one of the other filters available would be better at increasing contrast without imparting so much color.

                    Comments about Celestron Telescope UHC/LPR Filter - 2 Inch:

                    Happily the background sky looks natural through this filter and many stars are visible - I didn't know what to expect. The summer conditions have only allowed me to view the Ring and Dumbbell Nebulae under fairly light polluted conditions, but that was encouraging enough that I now look forward to more extended nebula and better seeing.
                    The filter threads seem to work ok in some eyepieces but get stuck in others. This may have to do with the different makes of EPs, adapters and barlows that I use and is probably not a filter issue. So far this filter looks very good.
