Anyone used a CLR ?

I'm looking at purchasing a new telescope (one with an alt-azimuth mount [and also a couple of extra inches]) -- and one of the accessories for one of the telescopes that I'm looking at comes with a Conurbation Light Reducer ("Fog Filter"); and it explains what it is, etc.

They make it out to be very good, and to pretty much eliminate the problem of light pollution -- but I'm a little skeptical.

Has anyone tried one out before? Are they really that good? Or a bit of a disappointment?

    Accepted Solution

    I have one in my Meade telescope - it takes the form of a light pollution filter to block out streetlight wavelengths, so it does work, but it cuts down on the available light.  This means it benefits clock-driven CCD camera exposures, but is not beneficial for eyeball viewing (you actually get less light).  I strongly advise you to get an equatorial mount if you want to do stargazing, because it will make tracking much easier, and allow you to upgrade to clock drive in the future (if the telescope allows that).
