Review CELESTRON Nexstar Portable Computerised Maksutov cassegrain

The Celestron NexStar 90SLT-Mak Computerized Maksutov-Cassegrain Telescope is a versatile and user-friendly astronomical instrument designed for both beginner and advanced stargazers. This telescope boasts a compact and portable design, making it an excellent choice for observers who wish to explore the night sky from various locations.

At its heart is a high-performance Maksutov-Cassegrain optical system. This design combines the benefits of both reflecting and refracting telescopes, delivering sharp and clear images with high contrast and minimal distortion. The 90mm (3.5 inches) primary mirror gathers a significant amount of light, allowing for a wider field of view and increased sensitivity, making it suitable for observing a wide range of celestial objects, from bright planets and the Moon to binary stars, nebulae, and galaxies.

The NexStar 90SLT-Mak comes equipped with Celestron's NexStar computerized hand controller. This user-friendly interface allows users to select and track over 40,000 celestial objects with ease. The database includes stars, planets, galaxies, and more, ensuring that you'll always find something fascinating to observe. The hand controller also allows for manual slewing and alignment procedures, providing the flexibility to explore areas of the night sky outside of the database.

One of the standout features of this telescope is its ability to be used as both a visual and imaging instrument. The inclusion of a Mak CAS Collimator ensures that the telescope is easy to collimate, ensuring that the optical components are correctly aligned for optimal performance. This makes it ideal for astrophotographers, who can attach a compatible camera and capture stunning images of the cosmos.

The NexStar 90SLT-Mak is also equipped with a sturdy and adjustable aluminum tripod, which can be easily extended to accommodate different user heights and observing conditions. The telescope's lightweight design makes it easy to transport and set up, allowing for a quick transition from day to night activities.

In summary, the Celestron NexStar 90SLT-Mak Computerized Maksutov-Cassegrain Telescope is a versatile and powerful astronomical instrument suitable for both beginner and advanced stargazers. Its compact and portable design, high-performance optical system, and user-friendly computerized hand controller make it an excellent choice for those seeking to explore the night sky in detail and capture stunning images of celestial objects.

The Celestron NexStar 90SLT-Mak is a computerized Maksutov-Cassegrain telescope, which offers several advantages and disadvantages for astronomical observing.

1. Compact and Portable: The NexStar 90SLT-Mak is a relatively lightweight and portable telescope, making it an excellent choice for stargazing on the go. It comes with a sturdy tripod and a carry case, which makes it easy to transport.

2. Computerized Operation: The telescope comes with a database of over 40,000 celestial objects that can be easily located using the Starpointer finderscope and the NexStar hand controller. This feature makes it an excellent choice for beginners and intermediates.

3. High-Quality Optics: The Maksutov-Cassegrain design of the telescope offers a high degree of optical quality, which is essential for observing faint objects and fine details. The telescope also comes with a 90mm primary mirror, which provides a good balance between light-gathering ability and portability.

4. Easy to Set Up: The telescope can be set up in just a few minutes, making it an excellent choice for observing sessions on short notice.

1. Limited Aperture: The 90mm aperture of the telescope limits its ability to gather light, which can make observing faint objects more challenging.

2. Limited Tracking Capabilities: The computerized tracking of the telescope is limited to a certain extent, which means that long exposure astrophotography may not be possible with this telescope.

3. Limited Payload Capacity: The telescope has a limited payload capacity, which means that heavy eyepieces or accessories may not be compatible.

The Celestron NexStar 90SLT-Mak is an excellent choice for astronomers who are looking for a compact, portable, and easy-to-use telescope with high-quality optics. Its computerized operation makes it a great choice for beginners and intermediates, and its Maksutov-Cassegrain design offers excellent optical performance. However, its limited aperture and payload capacity may make it less suitable for observing very faint objects or using heavy accessories.

If you are looking for a portable telescope with high-quality optics and computerized operation, the Celestron NexStar 90SLT-Mak is an excellent choice. It is an ideal telescope for observing brighter celestial objects such as planets, the Moon, and bright stars. However, if you are interested in observing very faint objects or doing astrophotography, you may want to consider a larger and more expensive telescope with a larger aperture and better tracking capabilities.
