Expert comment:
According to our assessment, LightBridge Dobsonians are the currently best series Dobsonian on the market. LightBridges not only have good portability, but also show good workmanship. Their design means that they hold collimation well, and also the focuser is of good quality.
The 2 inch wide angle eyepiece supplied with them is a perfect match. Their only weak point is the finder. The red dot arrangement takes some getting used to. We recommend purchasing a additional finder scope with an extra finder scope shoe. And, generally, 2 more eyepieces for medium and high magnifications as well as a nebula filter are important additions!
