Product Description

A 45 degree erect image diagonal for correct image views in daytime with Refractors, SCT's and Maksutovs. A quality coated prism designed to accept any standard 1.25" eyepiece, this prism will fit Telescopes with a 1.25" focuser. The 45 degree angle of this model makes it especially suited to normal land viewing where the instrument is near horizontal.

Further details

If you look through your telescope with the standard mirror or star diagonal installed, you will notice that objects may be either upside down, flipped so that you see a mirror image, or a combination of the two. This is fine for observations of celestial objects, but it can be a little confusing when you are trying to track a boat as it moves through the water, or an eagle as he flies towards his perch.

Luckily, this is an easy problem to correct. Simply remove the standard diagonal from the telescope’s focuser or visual back, and install the Erect Image Diagonal. Now, when you insert an eyepiece, objects will be right side up and left-to-right correct. The 45º angle of this Amici prism diagonal is very comfortable for daytime observations, where the telescope is often in a horizontal position.

Customer Reviews

10/10  SkyWatcher 45 Degree Erecting Prism  Most useful bit of kit. Turn your telescope in any direction and you know your eyepiece image will be the right way up and follow in the same direction. Also, as a pensioner, it makes star gazing easier from a seated position.....   (23/01/2018) Rob H. - Torbay
