If you want to do quick focusing testing which I assembled scope for the first time 1) If you have bigger room size put your telescope at the other end of the room 2) On small piece draw a 10 cm rectangle or square on plane paper write couple of lines with height not more than 5-10 mm inside circle or square 3) Stick the paper on plain wall and distance between telescope and wall should be 3 to 4 meter 4) From finder scope try to focus on circle or square and gradually try to find text you have written This technique is useful to find whether your scope is assembled properly and can do basic focusing
