Celestron 45 Degree Erect Image Diagonal

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 Celestron 45º 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.

Please Note: Not suitable for Newtonian Reflectors

Use your Refractor, SCT or Maksutov Cassegrain for fully corrected daytime views with this diagonal

  Excellent product.  Apart from converting the scope to a terrestrial it makes it much more comfortable for lower sky viewing. There is no loss of image quality when using this as I have experienced with less expensive equivalents. Highly recommended.  (15/11/2020) Ken - Shropshire

  Does the job perfectly  This erecting prism allows me to use my Celestron 127-SLT as a spotter scope, by turning the image the right way up and making left and right movements intuitive. It works beautifully and is a great help. As ever, the advice and super-quick service from Harrison Telescopes was outstanding. Thanks!   (31/08/2018) Boz - London, UK
