A sealed tube, a lens at the front, and colour to account for · review
A 70/400 refractor sold as a first instrument for children from eight, supplied in a backpack with three eyepieces, a star diagonal and an erecting lens.
The bottom line A complete and portable first set whose limit is written into its eyepiece fitting rather than into its optics.
A 70 mm objective and a 400 mm focal length, both printed in the title. The first decides how much light arrives, the second decides how tightly the sky is framed and what magnification any given eyepiece produces. Divide the second by the first and the focal ratio is f/5.7 — a short, wide instrument rather than a planetary one.
The supplied-items list names the three eyepieces as 24.5 mm. That is the old narrow barrel, and it is the single fact that decides what this telescope can become: the eyepieces that would improve it are not made in that size in any useful number. A set bought on this fitting is a set used as delivered.
A backpack, a 5x24 finder, a star diagonal, a 1.5x erecting lens, a tripod and a phone holder, all listed by the maker. The erecting lens and the diagonal between them cover both daytime and night use, and the phone holder is there for the Moon.
A child who will carry it. The 400 mm tube and the backpack are the point of the design, and the short focal length keeps the low-power view wide enough to find things without a good finder.

Only within the 24.5 mm fitting, which is the difficulty. The supplied-items list names the eyepieces as 24.5 mm, and the modern ranges are 31.75 mm and 50.8 mm. That makes this a set to use as it comes rather than one to upgrade.
It turns the image the right way up, which matters for landscapes and not at all for the sky. It also lengthens the light path, so it changes where focus falls.
