Superb image, Pavel!! I didn’t know such fine detailed gas are shown up.

This is further update on 0.7x reducer. The picture shows how M48(=2″) filter is set in front of lens barrel. The reverse attachment doesn’t lose effective lens aperture originally designed. At least any IDAS filters don’t matter which surface is faced toward the objective side.

Also although rotating function is added after the prototype, it’s well designed and made!! Very steady and no play at all. Very good extra value.
