Telescopes with a Red dot viewfinder

With spot guidance (LED)

— a finder that works similarly to a red dot sight: it is equipped with a viewing window in which a light mark is visible (in the form of a dot, circle, crosshairs, etc.). This design is more convenient than the optical one in the sense that the observer does not need to stick close to the finder — the mark is clearly visible at a distance of a couple of tens of centimeters, and this distance does not need to be maintained exactly. In addition, the light pointer is perfectly visible against the dark sky. Among the disadvantages of LED finders, it is worth mentioning the complexity, high cost, the need for a power source and poor suitability for use in bright skies. It should also be taken into account that such systems usually do not provide magnification, unlike optics; this in itself is not a disadvantage, but in some situations it can be inconvenient.
