Design features and use
Achromatic refractor Navigator 70400 little reacts to changes in temperature, rarely requires re-alignment and builds a great contrast of the image. Achromatic objectives lens corrects chromatism of primary, of secondary chromatism is reduced due to the small relative aperture of 1:6 telescope.
Includes 3 eyepiece:
- 5 mm (80x), for a detailed study of the moon and planets;
- 9 mm (44,5 x), for small galaxies and planetary clusters
- 20 mm (20x) to observe deepsky objects
Lens Barlow 3x 3 times enlarges the magnification of the telescope. Diagonal prism, mounted in front of the eyepiece, not only ensures a correctly oriented image, but also highly comfortable viewing located objects.
