Best light pollution filter?

[Jim123]

Deciding whether or not it is worth getting one and if so which one is the best... Any ideas?

[Psychobilly]

It really depends on the sources your trying to counter...

I have to counter the older sodium lights and use Hutech IDAS filters I have them in 2" and MFA format and I am currently waiting for a 77mm front filter to turn up for use with a full frame camera and camera lenses...

I have also used the Astronomik CLS and CLS-CCD filters and Lumicon Deepsky for me the Hutech IDAS is the best filter which does a superb job and introduces little or no colour cast... It also takes care of the UV/IR cut requirements for my full spectrum modded camera...

+1 for the Hutech IDAS

Another vote for the IDA'S from me too - it simply works without imparting a colour cast.

Can these be used "in line" of the LRGB filters, in the nosepiece in front of the filters? Seem to recall folk saying you can but not a definite Yes... !
