Filter thread

Left a 1.25" and right a 2" eyepiece with filter attached Left a 1.25" and right a 2" eyepiece with filter attached

Use filters for your observing: most astronomical eyepieces offer you the option to use moon filters, polarizing filters, colour or nebula filters. This will improve your observing experience and reveal a number of details that were previously not visible to you. At the lower end of the eyepiece sleeve of your 1.25" and 2" eyepieces you will find a female thread. You can use this to attach any filter from our range.
