CA introduced by compensating eyepiece?

Would a Leitz Periplan eyepiece add Chromatic Aberration to the image formed by a Nikon CFN objective? I've read a lot about CA introduced by pre-CF objectives if used without the corresponding eyepieces, but is it also a problem the other way round?

Regards,
Martin

Yes, it will do, and just the opposite lateral CA.

Thanks for your prompt reply, Pau.
Drat!

I'd appreciate any recommendations for eyepieces that are compatible with these Nikon CF N objectives.

Just curious... why not look for Nikon CF eyepieces (like the CFW10X)? These were made to be used with these objectives, are of excellent quality, and they are quite common.

Thanks for the comment Charles. The CFW eyepieces are an obvious choice, now that I know that they were made for the CF lenses, which I didn't before...

The Nikon CFWN X10 eyepieces are truly excellent partnered with CF objectives. Also they do not seem prone to delamination and are often available at significantly cheaper prices than Zeiss and Leitz eyepieces of similar quality. If you would like the details of the supplier in the UK that I got my used pair from please drop me a PM.
