Celestron telescope reflector cassegrain eyepiece 1.25" Green #58 filter JAPAN

Description

This auction is for
a wonderful-surviving 1986 Celestron (Vixen or Nihon Seiko of Japan) 1.25-inch Green #58 color filter. It will come with its original plexiglass storage case as well as the original print instructions and box.
This is real-tinted Japanese glass that will not have pitting or peeling issues. It is extremely durable and will give even color throughout the visible plane.
Made of milled aluminum and tinted plate glass.
The Green #58 is the perfect filter for use on 3-inch to 10-inch telescopes in seeing Jupiter's Great Red Spot when it is at less ideal conditions (Jupiter's GRS does indeed change in intensity even during the same night), it also enhances the color differences of the Jovian bands, it will definitely increase the contrast of Mars' polar caps in a 4-inch refractor or larger telescope, I think it is the second best filter to use on Venus for picking-up ANY subtle atmospheric shading in any scope over 3-inches, and for Saturn it will make the cloud bands stand out more clearly; especially in 5-inch or larger refractors and in 8-inch or larger reflector-style telescopes.
This filter will thread to nearly ANY 1.25-inch eyepiece that has female threads on its lower barrel. Whether from Japan, USA, China, Taiwan, or Russia (Soviet Union if by TAL depending on years), it should not be an issue. Below, however, are specific instances in which this filter will not work with a 1.25-inch ocular.
This filter will not thread to eyepieces branded Criterion, Bausch And Lomb Criterion, Vernonscope, Brandon, and/or Questar. This filter may have issues fully threading to the very first years of the Tele Vue plossls and Wide Fields with the "NJ JAPAN" inscriptions.
Packed with great care.
