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. • Never leave the telescope unsupervised, either when children are present or with adults who may not be familiar with the correct operating procedures of your telescope.
