ALTER M500

This most compact of all Intes Micro Maksutov Cassegrains already has all the great features of the larger models. In addition it is extremely compact and portable. Good photographical tripods carry this telescope easily. This makes the Alter M500 an ultra-compact all-purpose telescope that is ideally suited for airline travelling. With the optional focal reducer (0.55x) you turn the Alter M500 into a powerful astronomical telephoto lens for top-grade Deep Sky astro-photography. The focal ratio is reduced to f/5.5 for shorter exposure times and a larger photographical field
