This is a quality telescope, optical tube is good. However, accessories from factory like eyepiece and diagonal are just so so. Will get more fun if replace with high quality eyepiece. The mount is a bit shaky especially doing high zoom. Not going out to test the starsense app yet. Seller is also knowledgeable to answer questions. Overall, it good and worth for the money, happy to get it. Thinking to change a mirror diagonal for a better astronomy experience.
