Worth knowing before you buy
The focuser tube is plastic and can develop wobble or play over time, causing slight image shift during focusing adjustments.
The secondary mirror holder occasionally shows misalignment issues out of the box, requiring users to perform collimation before first use.
The included laser collimator is low quality and can be unreliable for accurate collimation, leading many owners to purchase a better alternative.
