The Messier AR-127S on the EXOS-2 GOTO is a combination of the 127mm fine quality of the Petzwala lens (four-element neoachromat) and the great German assembly with the Bresser / Meade AutoStar search system.
A great set for advanced astrophotography, a favorite telescope for middle and high school schools!
Messier AR-127S is a high-quality achromat refractor dedicated to advanced visual observations and astrophotography. It is equipped with a lens with a diameter of 127 mm and a focal length of 635 mm made of 4 lenses (Petzwala type construction). Thanks to this, despite the large light, the telescope is characterized by a large flat field of vision and a perfect correction of chromatic aberration. In the visual observations of the planets and the Moon it works perfectly, showing many details of the surfaces of the Solar System objects. Among the deep sky objects, you can see hundreds of nebulae from the Messier and NGC catalogs. The optics are fully covered with anti-reflective layers (MC). Equipped with a 4-inch (4-inch) focal length with the possibility of reduction to 2 inches and 1.25 inches. The MC layers on the lens significantly increase the contrast of obtained images and the eyepiece extractor allows the use of any spectacles made in 2-inch and 1.25-inch standards. This telescope is an excellent choice for advanced sky observers.
Assembly BESser EXOS-2 GOTO is a rigid tripod with a parallactic head equipped with a system of electronic search and positioning of GO-TO objects. Independent motion in the axis of right ascension (RA) and declination (Dec) takes place smoothly and evenly (with a small PE period error) thanks to four precision steel bearings. Precision worm gears allow the telescope to rotate and precisely track objects. Nine speed ranges allow you to quickly set the telescope to the desired area of ••the sky.
The drive can be powered by 8 R20 batteries, through a cigarette lighter socket or with the help of an AC adapter.
The assembly is intended for demanding observers. The AutoStar Meade # 497 system with GoTo system and a database of 30000 objects enables easy searching and tracking of planets, stars, star clusters, galaxies and satellites. The AutoStar controller has attractive routes in its database. Just enter the date, time and location. The AutoStar driver can be updated via resources available for download from the manufacturer's website (www.Meade.com). For example, you can download information about new comets and enter them into the assembly control database.
Solid construction, excellent installation finish combined with a stable tripod allows for visual observations and top-level photography.
This assembly is a modernized version of the Meade LXD75 assembly - it cooperates with cables and drivers for Meade LXD75 assembly.

Assembly photos EXOS-2 GOTO
This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.
