What we liked
- + Cheshire design needs no batteries and never goes out of alignment itself
- + Shows primary and secondary mirror alignment together for accurate results
- + Celestron build fits snugly in standard focusers
Trade-offs
- - Requires some light in the tube and practice to interpret the view
- - Slower to use than a laser, especially for complete beginners
