This book is a concise, fully illustrated guide on how I restored a telescope that was in poor condition when I purchased it recently at a local car boot sale. If you own a Celestron 70AZ refractor or similar telescope and want to perform your own servicing tasks, this resource should prove useful. Additionally, it may also appeal to those who enjoy picking up a bargain from car boot sales, table sales, online marketplaces etc. for little cost and after performing restoration tasks, either use their purchase to observe the night sky or resell their telescope find at a higher price.
