Porro telescope has the advantages of low price and good effect, but the volume and weight are about 40% larger than that of roof prism telescope of the same specification. The nearest observation distance is far, and it is not suitable for bird watching and other occasions that require close observation.
The advantages of roof prism telescopes are small size and weight, good portability, short observation distance, suitable for bird watching, but high technical requirements, cheap models cannot obtain excellent picture quality.
Generally speaking, when the budget is less than $50 USD, unless the volume and close-range observation are particularly important , the porro telescope is preferred. If the budget exceeds $50 USD, the roof prism telescope can be considered. The budget is more than $167 USD, and the roof prism telescope is mainly recommended.
