The Astronomik CLS and CLS-CCD

[pmesquita]

I have CLS filter for ASTROPHOTOGRAPHY light polluted skies.

I bought it because it is practically the same as the new CLS-CCD and the difference is only in three transmission levels. The CLS has a 92% ratio and the new CLS-CCD has a raito of 95%. So I didn't get the CLS-CCD because I believe it is more of a marketing revamp of the original CLS...which is still sold as an AP filter and is cheaper. Check out the website:

Astronomik -CLS*filter-

Any inputs on this?

The CCD CLS has IR cut whereas the standard CLS hasn't. If you're imaging and don't want to use a separate IR cut filter, you need the CCD version, hence the name

So the CSL is actually more versatile... If one has an IR cut filter on the side...

thanks for the input.

cheers.

Not really, as you can still use the CCD CLS for visual use. It's just the CCD version is more expensive.
