5 F or e xample, the GoScope has a focal length of 350mm, which when used with the supplied 20mm ey epiece yields: 350mm = 17.5x 20mm The magnification provided b y the 10mm eyepiece is: 350mm = 35x 10mm The maximum attainable magnification for a telescope is directly related to how much light it can gather .
6 T o see what y ou’ re doing in the darkness, use a red-filtered flashlight rather than a white light. Red light does not spoil your e yes’ dar k adaptation like white light does. A flashlight with a red LED light is ideal, or you can co ver the front of a regular incandescent flashlight with red cellophane or paper .
7 Car e and Maintenance If you give your telescope reasonable care, it will last a life - time. Store it in a clean, dr y , dust-free place, saf e from rapid changes in temperature and humidity . Do not store the tele - scope outdoors , although storage in a garage or shed is OK.
