Levenhuk Skyline PRO 105 MAK is a catadioptric telescope of Maksutov-Cassegrain design that delivers high-quality views while remaining compact and lightweight. The 102-millimeter (4-inch) aperture gathers 28% more light than a 90-millimeter (3.5-inch) counterpart, and the telescope's long focal length – 1300 millimeters (51 inches) – allows for high magnifications that deliver sharp images during observations and astrophotography. This telescope may also be used for observations of deep-sky objects, like planetary nebulae and star clusters. With the help of an erecting prism (purchased separately), you can turn your telescope into a powerful spotting scope for terrestrial observations. It can even be used as a long-focus lens for SLR cameras, and is adaptable to regular tripods.
The lenses and mirrors are fully multi-coated, which allows for maximum light-gathering and increases their service life. The sturdy and lightweight aluminum tube is set up on an equatorial mount with slow-motion controls. You can also install the equatorial computerized drive system (purchased separately) on your mount. This mount is equipped with setting circles which – after a quick adjustment – allow for locating objects by their celestial coordinates and tracking them with just a turn of an equatorial control. The adjustable height tripod has a practical accessory tray where you can store all your tools. The Red Dot finder scope allows you to quickly navigate to the desired location. The kit includes 10-millimeter (0.4-inch) and 25-millimeter (0.98-inch) eyepieces with 52-degree field of view of 130x and 52x magnification, respectively. The lenses are made of glass and are fully multi-coated. Focusing your telescope is as easy as adjusting the primary mirror with a move of the smooth-turning knob. The rack-and-pinion focuser is made of stainless steel and accepts 31.75-millimeter (1.25-inch) eyepieces; so you can use eyepieces purchased separately – not just those supplied with the kit – therefore increasing the magnification to the highest practical power of 200x. The focuser has the standard T-thread, which allows you to attach an SLR camera using an adapter and use your telescope for astrophotography.

And one more question... In the article I noticed one curious thing... refractors that are gathered together with reflector and catadioptric telescopes in sections always have smaller aperture than other telescope types. As I figured it must mean that reflectors and catadioptric telescopes lose in comparison with refractors... Is it a fair conclusion?
Thank you in advance!!!
Yes, catadioptric telescopes gather less light than telescopes of other types with the same aperture (about 65-75% while refractors gather 90%). Advantages of catadioptric telescopes: large focal length; despite their size - convenient for maximum magnifications (planetary observations); almost no color and geometric distortion.
Thanks for the query.
In this case, to calculate the highest mm. of an eyepiece, we need to divide the telescope's focal length by the highest practical power which makes it 6.37mm.
I doubt that an eyepiece with exactly the same focal length exists so you need to choose one of the closest, for example, Levenhuk Plössl 6.3 mm Eyepiece.
I'd recommend to check out a "See it all!" Astronomer's Handbook which includes information on 280 celestial objects. You may find it here at http://www.levenhuk.com/catalogue/other/books-charts-and-posters/see-it-all-astronomers-handbook/
