A 16-inch telescope is one of the largest telescopes for amateurs and hobbyist sky gazers. The large aperture can gather a large amount of light, making the views of planets and other night sky objects sharp. Serious astronomers also prefer this scope for the amazing views and optical performance. The magnification allows them to research […]
A 15-inch aperture offers a light-gathering power 4 times that of an 8-inch Schmidt-Cassegrain telescope. Amateurs will get amazing detailed views of the deep night sky objects with it. Obscure galaxies will appear with real color and details. However, there are not many options for a 15-inch telescope available on the market. Obsession Ultra Compact […]
