Our Content Types

Review Posts are based on hands-on experience and direct testing of telescopes and astronomy gear. Overview Posts are based on in-depth research, manufacturer data, astronomy community feedback, and independent testing data from trusted sources. Both types aim to give you clear, honest, and useful information.

Our Rating System

For review posts, our ratings are based on first-hand use and expert judgment. For overview posts, our ratings reflect aggregated insights from reputable sources and verified user experiences.

Where to buy?

Consider choosing HighPointScientific as your main vendor for shipping safety and refunds. Amazon is viable, but has occasionally shipped astronomy gear with missing pieces and more complex refund processes.
