Intes Micro Alter 715 Deluxe Maksutov Cassegrain teleskop

With its long focal length of 2670 mm and f/15 it is best suited for high-resolution lunar and planetary work (visually and imaging). It is possible in principle to reduce the focal ratio with an old Celestron 0.63x reducer down to 1680 mm and thus use it also for imaging of smaller galaxies but this it not where this instrument shines.

You can watch a YouTube video by Ed Ting about such a scope here:
