An entry-level refractive telescope that is suitable for an introduction to astronomy for schoolchildren and preschoolers. Comes with tripod, mounts, viewfinder and carrying bag. Easy to assemble, install and use, it is comfortable enough to aim at objects using the viewfinder. Allows you to get basic knowledge in astronomy and confirm the knowledge gained in the classroom.
The advantage of such a kit is that for relatively little money you get a simple entry-level telescope on a turnkey basis, that is, with all the necessary equipment (viewfinder, rotary prism), a tripod for installation and a backpack for carrying. And such a telescope is suitable for observing the moon.

- Kit weight: ~1.4 kg
Supplied as a large set in a carry bag, with tripod, eyepiece and viewfinder. Also included is a swivel prism. The tripod comes with its own case. There are several compartments in the backpack, in which the components of the telescope are laid out.
Instructions in Russian, quite detailed and describing the main points of use: assembling and installing the telescope on a tripod, setting the viewfinder, focusing on objects, as well as information on maintenance and cleaning of elements.
Complete tripod SVBONY SV101 metal, with height and tilt adjustment. The maximum lifting height is 138 cm.
The body of the SVBONY telescope resembles a small spotting scope or monocular. The only thing that distinguishes it from similar optical devices is the presence of zoom adjustment and a relatively large entrance lens (70 mm). Mounts for the viewfinder and tripod are also already installed on the body.
As I said, the entrance lens is 70mm/400mm (F5.7). The total length is increased by a massive hood that covers the lens from light.
The body of the telescope is made of metal, but all moving parts and connections are made of plastic. Screws are provided for fixing the position and components of the telescope.
For ease of observation, a 45° rotating prism BK7 is used. If you choose the SVBONY SV501 model, then the prism in the kit will already be 90°.
The kit also includes an eyepiece with a magnification of 20x. The landing size is standard (1.25″), you can choose another option for this size by changing the general parameters of the telescope.
Don’t forget to install the viewfinder. It represents a simple search telescope 5×24 with a crosshair on the lens, for searching and capturing the object of observation. The viewfinder has a much wider field of view and is much easier to navigate. After capturing the object in the crosshairs, you need to fix the tripod adjustment screws from moving from the adjusted position.
The tripod uses a dovetail mount. It is installed in the counterpart on a tripod. Next, we fix so that there is no excessive chatter.
This is what the assembled SVBONY SV501P telescope looks like before being mounted on a tripod. Keep in mind that it will not work with hands. You will definitely need a tripod or stop if you use it as a magnifying tube.
We choose quiet windless weather, it can be frosty. The main thing is that there is no haze or fog, as well as clouds. The photo shows a telescope prepared for shooting at midnight.
We aim with the help of the viewfinder at the object of observation. The best result will be for observing the moon — the only object available to this telescope. After aiming, tighten the tripod lock, otherwise you may lose sight of the object.
For comparison, the stars look through a telescope like ordinary dots through a magnifying tube. It makes sense only to consider the constellations, without details, and correlate them with a map of the starry sky.
As for the moon, here is something like this image that allows you to get a leaning smartphone camera. There are nuances of smartphone focusing, so the picture came out a little blurry. You can try using filters for telescope lenses (diameter 70 mm).
Also, image clarity can be achieved by adjusting the eyepiece and the zoom of the tube. Special astrocameras give an image much better. Visually, the eye can see such a picture (with magnification).
And another example of observing the full moon. Sufficiently detailed image, you can see the craters and other objects on the surface.
Thus, such a telescope allows you to get basic skills in astronomy, to examine the picture of the starry sky. It will be useful to “feel what telescopes are” in principle, but without overpaying for expensive models. It must be understood that all such telescopes give a rather mediocre image, insufficient magnification to examine individual stars and poor workmanship in general. The only thing the SVBONY SV501P is better than the rest of its kind is a decent sharpness that allows you to view the moon in detail and see the wonders of the night sky for the first time. In addition to night observations of the moon, the telescope can be used as a regular telescope / magnifier or monocular. You can buy the SVBONY SV501/SV501P telescope model from stock in Russia, delivered in 4–5 days.
