I like to use a polarizing filter, or better yet stack two together, which makes a variable polarizer. They are usually made in standard sizes to fit into the bottom of the eypeice, 1-1/4″ and 2″.

You really don’t need a filter for astrophotography. The moon is very close to the tone of a gray card used for setting exposures. It’s the easiest object to get the exposure correct for. Depending on how you are taking pictures, you may need all the light you can get. If you are using eyepiece projection through your camera lens, then you really don’t want to filter. If you are connecting the camera directly to the telescope, you won’t be able to use the filter unless your camera adapter has threads for one. In any event, try it without one and I think you’ll be pleasantly surprised.

To answer your question, as the others have, any moon filter the size for your eyepiece will work for you.

+Filters screw onto the bottom of the eyepiece. So as long as you have a standard 1.25″ eyepiece it will be fine.

A moon filter is just a neutral density filter that screws into the bottom of the eyepiece barrel. As long as your eyepieces have screw threads at the bottom anyone’s filters should fit. All you need to do is get the appropriate size for your eyepieces, most of which are 1.25″. You don’t really “need” a filter to observe the moon, though observing without will trash your night vision for a while.

why do you think you need a moon filter? most people are mistaken when they ask questions about filters.

eyepieces (and filters) are standard sizes. they are readily interchangeable.
