The telescopes come mostly assembled. Users will need to insert the main eyepiece (25x) into the wide end of the Barlow tube and the auxiliary eyepiece barrel into the narrow end of the Barlow tube; then insert this assembly into the focuser of the Galileoscope to get a magnification of 50x. Or, to make the Galilean eyepiece with a magnification of 17x, take the auxiliary eyepiece cap and place it over the auxiliary eyepiece barrel; then insert the Galilean eyepiece into the focuser tube of the telescope. Includes V-block bases/stands. Also includes an information sheet (with assembly, focusing and aiming instructions). | |
