I have a set of older Astromiks. They are fairly good. My main problem with them was they are so thin and for some filter wheels needed packers. The new FLI Filter wheels have a clever set of washers that suit any thickness.

Are they 1:1:1 RGB combine?

Do you find they are parfocal or do they need different focus points? Same with the narrowband. I can focus with the luminance with Astrodons and the narrowbands are also in focus which makes it a lot easier to focus them.

I like the sound of tuning your luminance and in particular a Light pollution filter. But sadly they don't seem to sell a CLS filter in 50X50mm.

Greg.
