Good optics and precision mechanics cost money, and to a large extent, you get what you pay for. Partly it’s because the comparison is inherently unfair. Yet many, many scopes fall short of this benchmark. In my experience, a well made and adjusted reflector is capable of holding its own against a premium apochromatic refractor - an instrument synonymous with optical perfection. The more you know about your Newtonian reflector’s potential and its pitfalls, the better equipped you’ll be to ensure it’s delivering peak performance. Whether homebuilt or commercially manufactured, a good Newtonian can rival the performance of any optical design. The Newtonian reflector is one of the most versatile optical configurations ever created.
