Hi Greg,

You need to compare them on a lot more targets than just one and more specifically a few targets that are threshhold targets for the aperture you are using, and not something that gives you sunburn of the eyeball. Not saying the Russell isn't a good eyepiece, just that you can't form any conclusions after viewing one target that is visible "naked eye".

Cheers,
