Your telescope is designed to give you years of fun and rewarding observations. However, there are a few
things to consider before using your telescope that will ensure your safety and protect your equipment.
Warning
• Never look directly at the sun with the naked eye or with a telescope (unless you have the proper solar
filter). Permanent and irreversible eye damage may result.
• Never use your telescope to project an image of the sun onto any surface. Internal heat build-up can
damage the telescope and any accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge. Internal heat build-up inside the telescope can
cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye.
• Do not leave the telescope unsupervised, either when children are present or adults who may not be
familiar with the correct operating procedures of your telescope.
