The NexStar 4SE is an excellent scope designed for both visual observations and astrophotography. With its built-in wedge mount, you can tilt the telescope like an Equatorial telescope, allowing you to compensate for the Earth's rotation and capture long exposure photography.

The Maksutov-Cassegrain optics - an efficient mixture of lenses and mirrors - produces an image that is very crisp for its compact size.
