Bresser Maksutov telescope MC 90/1250 Messier OTA (54564)

The traditional company Bresser offers telescopes under the Messier brand, providing an excellent price-performance ratio for ambitious beginners. These Messier telescope systems are expandable and retrofittable, making them suitable for use well beyond the initial entry point.

MC 90/1250 Telescope
This telescope is an excellent travel companion and serves as both an astronomical telescope and a mirror spotting scope for nature observation. It is also suitable for children taking their first steps in exploring the night sky. Its compact design allows it to fit into almost any hand luggage, making it highly portable. Known for its high-contrast images, this telescope features a 90 mm aperture, offering 165 times more light-gathering capacity than the naked eye (with a 7 mm pupil).

The saying "the best telescope is the one you have with you" perfectly applies here, as few telescopes are as easily transportable. Despite its compact size, this telescope offers excellent astronomical capabilities. With a resolution of 1.3 arcseconds, planets become fascinating objects to observe. Observing deep-sky objects like the Orion Nebula or scanning through the summer Milky Way is also highly enjoyable.

In addition to its astronomical uses, this telescope doubles as a spotting scope for nature observation and photography at an affordable price. Unlike many classical spotting scopes that require expensive fixed camera adapters, this telescope provides a wide range of adapters for nature photography. Its 1250 mm focal length makes it ideal for low-cost bird photography, and it can also capture stunning images of the Moon for astrophotography enthusiasts.

The sharpness of the image can be adjusted using a knob on the side of the telescope, which moves the primary mirror backward or forward. This mechanism provides a large focusing range, allowing compatibility with various accessories.
