Review on Celestron Erect Image Prism: Enhance Clarity for Refractor and Schmidt Cassegrain Telescopes by Robert Cooper
Corrects left/right and upside down image
comes with a telescope) corrects an upside down image (and puts the eyepiece at a right angle so you don't have to be on the ground to see) while the LR flip. Instead, this device corrects both flips. Good for things that need to look right like moon and ground objects.
Pros
- Like everything else
Cons
- No
