This green 1.25" filter screws onto standard 1.25" eyepieces and other accessories (like a Barlow) with 1.25" threads. Here are some of the most common uses for a green filter when it comes to observing our celestial neighbors: While this filter will make the moon look green, it will enhance the contrast between lighter and darker features, allowing you to see them better. A green filter can be useful when observing Venus. For daytime observing, it will help reduce the brightness of this "runaway greenhouse effect" planet. This is a good time to observe Venus, as the daytime sky provides less contrast and makes observing this super bright planet a little more comfortable. Increase the contrast of the polar ice caps on Mars with a green filter. A green filter enhances details in the atmosphere of Saturn. While the Great Red Spot...a famously huge storm on Jupiter...isn't nearly as big as it used to be, you can check it out by increasing its visibility with a green filter. While you are checking out Jupiter, that same green filter will enhance contrast of red, blue and white features in the atmosphere. Show more
