Celestron LPR Filter
A basic Broad Band LPR filter. This one is about as good as any other. The Broad Band filter _will_ increase contrast on nebula from mild to heavily light polluted sites. If you are expecting galaxys and star clusters to be vastly improved forget it! Spend the $60 for gas and drive out to dark skies.

not a bad filter for seeing nebulas, does what it suppose to.save your money and get a 0111 filter alot better. bob hart

Celestron LPR Filter
Same thing as the Orion or Meade filter. The construction of the Celestron filter seems very good. It will improve contrast on most nebulae. Really bright objects like the Orion show more detail even with a small refractor. However, this filter will work best on a telescope with a large aperature. I initially tried it on a 3.5" scope. Although it improves contrast, it will also dim the image quite a bit in a small scope. Also keep in mind that these do not work with stars, clusters, or galaxies.

All in all, it does what is supposed to do. Operationally, it works pretty good. Value wise, this gets a bit trickier. At full retail price, I don't think this is worth it. Save your money and buy a good OIII filter. On the other hand, if you can pick up one of these things used, it may be worth it. I picked mine up from Astromart for a steal.

Celestron LPR Filter
The Celestron LPR performs and looks about the same as the other broadband filters, but this one looked a little more special. The text on the eyepiece screw was red and nice looking, so I got this one (picky, aren't I?:).

This LPR dims the image in stars by about a magnitude or so in a 80mm refractor, but brings out more than 50% of detail on nebulae (you gotta take a look at the Orion, Crab, and other bright nebulae) and it seems to bring out some detail in the Andromeda and Pinwheel Galaxies when they're low on the horizon. It is almost useless under dark skies. When you hold it up and look toward the Vegas Strip lights, it turns some of the dark gray light pollution dark blue and softens the contrast of the orange lights. It's fun to look at a 100-watt light bulb through it ans read the text on the bulb.

Well, it's a great value for $60, and it reduces light pollution and enhances nebulae, but I'd save up for a Lumicon UHC filter ($100, works in dark skies, also) instead.

Pros- nice-looking, cheap, brings out detail in nebulae in light polluted skies, reduces weak light pollution, reduces glare

Cons- useless under dark skies, can't filter heavy light pollution

Celestron LPR Filter
I compared this filter side-by-side with an older Meade broadband filter and an Orion Skyglow, and the Celestron LPR was inferior in every respect. Construction, while good on the Celestron, was very inferior to the Meade, which had a heftier cell and much better threading.

This filter did not meet my expectations for even a basic light pollution filter. From my significantly light polluted skies, it increased contrast only slightly, while still transmitting more skyglow than the other two filters. As a result, the contrast gain on nebulae was only marginal and much less than in the Meade or Orion filters.

The only area that the Celestron excelled was that it permitted a higher transmission of stellar light and dimmed the background stars less than the other two.

My recommendaqtion - save up your pennies and get a narrowband filter, such as a UHC or Ultrablock. They are a much better investment if you purchase just one nebula filter.

Celestron LPR Filter
Lpr filter is a good option if you are thinking of suburban astrophotography,it realy enhances the views of most nebulae,m-57,m-42,m-27 were rich in contrast,the filter realy darkens the background sky but it would dim stelar images so it's performance is poor in open and globular clusters.
This filter allows you to duplicate your exposure times in a suburban sky,specialy good with Kodak E-200 film.
Good skies to all :-)

I Got mine used for £35 and so far i'm so pleased with the
results with my 12" Lightbridge.
Not so good in scopes 6" and under in my experience.
