Choosing the right telescope depends on your lifestyle and astronomical goals. There are certain factors that one should consider while buying a telescope. These are:
Size and portability: The size and portability of the device will have a significant effect on how often you can use it. While a bigger telescope will allow you to view more, it might also prevent you from using it regularly. Before purchasing a telescope, it is recommended to consider the amount of space you can afford to spare for it.
Performance: It is one of the key factors to consider before buying a telescope. Knowing what you want to see can help you find the right telescope. Similar to a camera lens, a telescope with a larger aperture will capture more light and allow you to see more objects in the night sky.
Design: The three most common telescope designs are refractors, reflectors and Cassegrains. Each one of them comes with different attributes. Study each design carefully to make an informed decision.
