2" CLS-CCD Filter - Which to get?

[AndyThilo]

Hi

I want to replace my UV/IR block filter with a CLS-CCD as I want to reduce as much light pollution as possible. However the pricing variation is pretty massive:

Altair Astro - £80

Optolong - £108

Astronomik - £179

I can't see the Astronomik being 2 times better than the Altair. Any opinions?

A dual/tri-band filter like the Optolong L-Enhance or similar?

I was specifically looking at CLS-CCD, I think the L-Enhance is very narrow band?

Hi, I have the astronomic cls (non ccd) and it performs very well as I use it on my newt, and have the ir cut separate or the L-2 luminance to stack with the cls to use with it when I use the frac etc. don'y know about others but I have the IDAS nb1 and ngs1 which are also pretty good as well esp for the OSC, hope this helps Tony
