The most aperture per euro, and an alignment to keep · review
A 130 mm Newtonian on a German equatorial mount with slow-motion controls, supplied with two eyepieces, a 1.5x erecting Barlow, a 13 % transmission Moon filter and a phone adapter.
The bottom line A generously equipped 130 mm let down on paper by the one figure the listing forgets to print.
The aperture is 130 mm, stated twice. The focal length appears nowhere in the listing. That is an unusual omission, and it matters: without it the focal ratio cannot be worked out, no magnification can be calculated, and the exit pupil of any candidate eyepiece is unknown. The figure will be on the tube; it is not in the advertising.
A German equatorial with setting circles and flexible slow-motion cables on both axes. Aligned on the pole, it follows a target with one control. Unaligned, it is an awkward alt-azimuth. That routine is the price of admission, and it is the same routine on every mount of this kind.
Thirteen per cent transmission, written as a number. Most Moon filters on this shelf are sold under a word. A percentage can be compared between makers; a word cannot.
The bullets describe a carbon-fibre coating on the tube. That is cosmetic and structural, and it tells the reader nothing about the mirror underneath — which is the part that decides what the telescope shows.

American and British Amazon stores list it in local currency, which the euro range above sets aside.

Because magnification is focal length divided by eyepiece focal length. Without it, no eyepiece decision can be made on paper — the figure has to come from the tube or the manual.
It passes 13 % of the light, which is a stated number rather than a name. A bright Moon at low power is uncomfortable; this cuts it to a level the eye can hold, and it is one of the few filter figures published plainly on this shelf.
