The steel tripod has markings so you can easily extend all legs to the same length. The azimuth and elevation clamps allow you to point the telescope at a target even without power. Up to seven eyepieces can be stored in two storage compartments - one even has a dimmable red LED light.\u003c\/p\u003e\n\u003cp\u003eMore power and safety thanks to lithium iron phosphate battery:\u003cbr\u003eInstead of a typical lithium polymer battery, a lithium iron phosphate battery is used in the Evolution telescopes.
