complete safety.  Eyepiece solar filters (not available from us) should be avoided at all costs as they 
are considered unsafe. 

 Note: Never look directly at the sun through a telescope without an objective solar filter! 

Q: I can’t see anything when I look through my telescope

 

A: The telescope is only suitable for astronomical observing and when used outside at night. 
Observing from  inside the house or during the day is not usually possible. 

 The dust caps must first be removed and an eyepiece inserted before you can start observing. Are 
you  sure you have you removed all the dust caps, not just the small ones? If you have not, then no 
light will  enter the telescope and everything will appear black.
