TPO #8 Light Yellow Color Filter & Case - 1.25"

Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue.

TPO filters are made of high quality, solid plane parallel glass with excellent homogeneity. They are anti-reflection coated to prevent glaring and ghosting. This eyepiece filter is threaded to fit most 1.25" eyepieces, and comes with a hinged, plastic case to keep your filter safe and clean when not in use.

#8 Light Yellow (83% transmission): Useful in observing red and orange-colored phenomena in the belts of Jupiter and in enhancing the level of observable detail of small orange-red zonal features within the belts of the planet. Increases contrast of maria on Mars. Can result in improved resolution of dusky detail on Uranus and Neptune in instruments of 10" aperture and larger. A popular filter for the enhancement of lunar features, particularly in telescopes of 8" aperture and smaller.

great communication

Ordered 6 telescope filters - turns out 5 were in stock, one was not. I then received direct and personal correspondence from a representative of Optcorp, advising me of the options. I made my choice, and the transaction then unfolded perfectly as planned and as I desired. In today’s world of commerce, this is not always the case. Thanks OPT!
