Telescopes optically invert the image which at the astronomical level is not of great importance. However, if we want to make terrestrial observations with our telescope, it is essential to add this accessory since without it we will see a north-south deformity or, what is the same, we will see the objects backwards.
The 45º inverter prism will be accompanied with the eyepiece that we want to use or we can add other additional accessories such as an image duplicator such as a barlow lens or a T adapter to take photography. This specific model is for the exclusive use of the Celestron Nexstar 4 SE telescope model.
Characteristics:
- Image inverter
- 45º
