I love this refactor

I absolutely love the scope. Crystal imaging and observing. I am giving a four-star rating due to the focuser. When I first unboxed there were several loose screws on the focuser, and two screws just fell to the floor. The focuser is not as smooth as I had anticipated. I highly recommend the scope. but be prepared to buy the upgrade.
