The 18 mm eye relief is 13 mm: this means that the image remains comfortable up to a distance of 13 mm above the lens, in order to take full advantage of the field offered by the eyepiece. This is an important detail for the viewer wearing eyeglasses, which will keep them on the nose.
The inside of the sink is threaded in M48 x 0.75 mm to accommodate filters with a diameter of 50.8 mm (2 "), Such as interference filters of type OIII, UHC, H-Beta..., Which serve to enhance contrast on many nebulae.
