In comparison, you can get an 8″ Dobsonian for that price, which has 4x the light-gathering power of a comparably-priced 4″ telescope! This translates to more overall detail in observing planets as well as being able to observe much fainter objects, so Dobsonians are especially great for observing galaxies and nebulae. Other than Dobsonians, telescopes in the sub-$500 price range rarely exceed 4″ in aperture due to their cost to produce. This is due to their large aperture and therefore light-gathering area. Even with a budget of below $500, you can get an excellent performing Dobsonian for visual observing.ĭobsonians can provide fantastic views of both deep sky objects and solar system objects like planets and the moon. This is due to a simple design that’s easy to manufacture large mirrors for an affordable price. Dobsonian telescopes offer the best bang-for-your-buck visual views of any telescope type.
