====== Apochromatic Refractors: ======
----Pros: Refractors are very convenient. They don't need collimation and are small making them portable. Their light weight makes them resistant to wind and their short focal lengths make them easy to guide with.

Cons: The small aperture makes them unusable for serious planetary imaging, and most are F/7 in focal ratio which is "slow", meaning you dont collect as much light per unit of aperture compared to other scopes. Smaller refractors tend to have shorter focal lengths, so are only really good if you want to image large targets. Larger refractors become increasingly expensive quite quickly.

'''Best suited for: Deep sky imaging.'''
