The Messier 8 "telescope is a breakthrough in Dobson's assembly, despite the low price, this telescope offers a lot of application and quality competing with much more expensive telescopes. Optics with a diameter of 8" (203 mm) give the possibility of observing objects in our Solar System and beyond. The telescope's diameter makes it possible to distinguish the light of individual stars in clusters, and nebulae almost imperceptible in smaller telescopes now reveal their structure. The high-quality, 6 "(65 mm) hexagonal focuser prevents vignetting even when using wide-angle spectacles, which is an unwanted feature of narrow extrusions .

Large wheels in the height axis ensure precision of movement even when using highly magnifying wide field spectacles. If heavier accessories are used, simply loosen the clamps and move the telescope tube slightly to balance the telescope.

The telescope uses a well-known extract from the 3rd generation of Messier telescopes based on a hexagonal profile with the ability to rotate, collimate the optical axis, adjust the travel force and equipped as standard with a single focusing system. This version of the extractor can be extended with micromancers with a ratio of 10: 1. The construction of the extractor allows the use of even larger and heavier accessories without the undesirable effect of displacement of the extraction sleeve. The high precision of the eyepiece used allows you to achieve optimum sharpness in a simple and quick way.

The possibility of disassembling the wheels of the height axis from the tube's sleeve and fixing the dovetail rail allows for fast adaptation of the tube to be mounted on typical paralactic assemblies.

The accessories included, such as the 6x30 finder and the 25mm eyepiece, make the set ready for observation.

Dismounted assembly, based on metal connections, makes it easy to store and carry the entire set.
