The main difference between a doublet and triplet refractor is a doublet has two lens elements, while a triplet has three elements that make up the objective lens. A doublet is the simplest lens system that works in telescopes. It is termed achromatic because it corrects for chromatic aberration. A more complex triplet lens delivers…
With an 8-inch Dobsonian telescope, you can see things like the terminator of the Moon, planets, star clusters, Orion Nebulae, and galaxies. You can also see the Rings of Saturn, Ring Nebulae, the global cluster in Hercules, the double stars, and deep sky objects like the Megallinic clouds and M13 globular. If you are looking…
A telescope extension tube is an additional, optional piece of equipment that can be added to a telescope. Its purpose is to increase the telescope’s focal length, making objects appear closer and magnifying them more. This helps make distant objects appear larger and sharper in the eyepiece. As your observing skills and knowledge improve, you…

The major differences between the Celestron C6 and C-8 are their aperture and weight. The Celestron C6 has a smaller aperture of 150mm, while the Celestron C-8 has a larger aperture of 200mm. The Celestron C6 has a focal length of 700mm, while the C-8 has 1000mm. The C6 is notably smaller and lighter than…
The main differences between Celestron and Gskyer telescopes are the type of mount, the quality of the optics, and the accessories that come with the telescope. The Gskyer comes in two types, a refractor and a reflector. The Celestron only comes in a refractor. The Gskyer has an alt-azimuth mount, while the Celestron has an…
