Review AMAZON BASICS Telescope 70mm Aperture 400mm Az Mount Portable Lightweight

The Basics BT1818 Telescope is an excellent choice for beginners or those looking for an affordable yet capable astronomical observing tool. This telescope features a 70mm (2.75 inches) aperture and a 400mm (15.75 inches) focal length, making it ideal for observing bright planets, stars, and constellations.

The telescope comes equipped with an Alt-Azimuth (altitude-azimuth) mount. This mount design provides a smooth and easy-to-use experience for users, allowing for simple adjustments in altitude and azimuth (right ascension). This makes it a great option for observers who prioritize ease of use over advanced tracking capabilities.

The telescope's objective lens, which gathers light to create the image, has a diameter of 70mm and is made of high-quality optical glass. This lens is coated with multiple layers of anti-reflection material to minimize light loss and improve the overall clarity and brightness of the images produced.

The telescope also includes a 20mm eyepiece, which provides a magnification of 20x when used with the telescope. This eyepiece is also fully multi-coated to enhance the image quality and reduce light loss. Additionally, the telescope is compatible with other eyepieces, allowing users to experiment with different magnifications and fields of view.

The telescope's tube is made of sturdy steel and is covered in a protective finish to ensure durability and resistance to the elements. The telescope also includes a sturdy tripod, which can support the weight of the telescope and provide a stable observing platform.

The Basics BT1818 Telescope is a versatile and capable observing tool, perfect for those looking to explore the wonders of the night sky. With its large 70mm aperture, smooth Alt-Azimuth mount, and high-quality optics, this telescope provides excellent image quality and an enjoyable observing experience.

The BT1818 telescope by Celestron, with a 70mm aperture and 400mm focal length, is a basic yet functional telescope suitable for beginners. Here are some pros and cons to help you make an informed decision:

1. Affordable: This telescope is priced reasonably for beginners who want to explore the night sky without investing a large sum of money.

2. Easy to use: The Azimuth Mount makes it easy to locate and track celestial objects as it allows the telescope to move in right ascension and declination.

3. Decent optics: The 70mm aperture provides a good amount of light gathering ability, which is essential for observing faint objects.

4. Portable: Weighing only about 13 pounds, this telescope is easy to transport, making it a great option for those who want to observe the night sky in different locations.

1. Manual tracking: The Azimuth Mount does not offer automatic tracking, which can make observing objects for extended periods challenging.

2. Limited magnification: The telescope comes with a 20mm eyepiece, providing a magnification of 20x. While sufficient for observing brighter objects, it may not provide enough detail for more challenging targets.

3. Limited filters: This telescope does not come with filters, which can be necessary for observing specific types of celestial objects, such as nebulae or galaxies.

The Celestron BT1818 telescope is an excellent beginner's telescope due to its affordable price, ease of use, and decent optics. However, its manual tracking, limited magnification, and lack of filters may limit its capabilities for more advanced observing. If you are a beginner looking for a low-cost, user-friendly telescope to explore the night sky, this telescope is a good option. However, if you are an experienced observer looking for more advanced features, you may want to consider a more expensive telescope.

If you are a beginner and are looking for a low-cost, user-friendly telescope to explore the night sky, the Celestron BT1818 telescope is a good option. However, if you are willing to invest a bit more money, consider the Celestron NexStar 4SE, which offers computerized tracking, higher magnification, and filters at a slightly higher price point. Alternatively, if you prefer a refractor telescope, consider the Celestron Astromaster 114AZ, which also offers better optics and more advanced features than the BT1818. Ultimately, the best telescope for you will depend on your observing goals, budget, and experience level.
