For those new to Astronomy, a few things to note:
1. These are for Refractor Telescopes (the skinny telescopes with lenses and NOT the fat ones that look like Cannons and have mirrors in them). The eyepiece gets inserted in these and allows the image on earth to be vertically correct so if you are looking at trees they will look right side up. However, if you are looking at a STOP SIGN, the letters will be backwards. This is normal. There is no right side up in space so when looking UP or astronomically, instead of terrestrially- or on earth, you'll be fine.
2. The diagonal mirror allows viewing from a direction that is at a right angle to the telecope tube resulting in more convenient and comfortable viewing especially when the telescope is pointed at objects directly overhead.
4. Mirror diagonals produce a high degree of optical accuracy and they do not introduce any color errors to the image.
PLEASE MEASURE YOUR TELESCOPE TO MAKE SURE THESE FIT AS THESE ARE 1.25" Format--and not the smaller version that is also available (.965" or just a bit UNDER 1" in diameter) so please check your telescope opening on the focuser to be sure.
