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.

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.
