Benefits include portability, compactness, and ease of installation and disassembly. It can be easily transported and stored, making it ideal for travel or use in small spaces. Its disadvantages include the stability and quality of the optics. Because the optics are not fixed in place, a collapsible telescope is usually less stable than a stationary telescope, which can make it difficult to get a clear image. In addition, its optics are more likely to suffer from misalignment and other optical aberrations, which can degrade image quality.
