#11 Yellow-Green Filter

I was a little skeptical about how much difference a filter could make, but the #11 Yellow-Green really brings out the cloud bands on Jupiter. The optical glass feels solid and the threads are smooth, no wobble when attached to my eyepiece.

The Schott glass really pulls through—saturn's rings showed a crispness I wasn't getting with my other filters. Moon craters at 200x had that sharp, three-dimensional pop. It's become a permanent part of my eyepiece case.

The contrast on Jupiter's bands jumped right out with this filter—way sharper than I expected. Even the subtle cloud details on Saturn came through more clearly. A solid upgrade for lunar viewing too.
