CA filters? What's your experience?

[emadmoussa]

What's your experience with refractors chromatic aberration? Which filters worked best?

I'm not sure this is the right section for this thread. Mr. Mod, please move it if required.

I had a Williams Optics CRV1 (I think it was this) and really hated the yellow cast it added to the view. it did work to some extent (on a 120mm f8 frac) but in the end I preferred the unfiltered view. that said I sold the scope once I tried my first newtonian.

In principle I'll be using a Rich field 152mm f/9 refractor - which by design supposedly has a significant chromatic aberration correction built in. The reviews I saw from people who use it were pretty positive But I guess despite all it'll need a filter to reduce/eliminate AC remnants if I want to use it at high mag on the moon or planets. I've seen good reviews on O-III filters. Haven't used any before and never cared much about a little bit of CA. But if I want to do high mag lunar imaging, I will probably need one.

I prefer unfiltered rather than swapping one false colour for another.

I do the same. Only for photographing filters seem of a benefit for me. Do you have a refractor?

I'd guess Peter probably has about 30 scopes of all different kinds, and just a few years' experience of using them
