Description

 

Sky-Watcher 1.25″ Erect Image Diagonals

Most of the telescopes work perfectly well during daytime as well as for astronomy. If you have a refractor or a Schmidt-Cassegrain telescope and you want to use it for terrestrial observations, Sky-Watcher Erect Image Diagonals are the most useful accessory you can buy.

Normally, the image created through the telescopes may be either upside down, flipped so that you see a mirror image, or a combination of the two. It will be very confusing when you are trying to track a moving boat or flying bird. This problem can be corrected easily by using a erect image diagonal

Simply remove the standard diagonal from the telescope’s focuser or visual back, and install the Sky-Watcher Erect Image Diagonal, then when you insert an eyepiece, objects will be right side up and left-to-right correct. These Amici prism diagonals are very comfortable for daytime observations, where the telescope is often in a horizontal position.

 

Please Note: Adding an erect-image diagonal to a Newtonian reflector will not result in images that are right side up and left-to-right correct. The optical design of a Newtonian will always produce images that are rotationally off in orientation. This does not mean that you can’t use a Newtonian reflector during the day, it just means that you have to get used to objects oriented in unrealistic positions.
