- General Notes:
- Avoid exposing the telescope to sudden temperature changes, as this can result in fogging of the objective lens as moisture condenses on it.
- If this should happen, place the object lens close, but not too close, to a source of heat and wait for the moisture to evaporate.
Caution:
- Never look directly at the sun with naked eye or with a telescope (unless you have the proper solar filter)
- Adult supervision is recommended when it is for use by children ages under 10 years old
