The following photographs were taken during the observing session at LRO, Lichfield, UK, by Andrew and Damian 17-18/11/2017. Photographs were taken from views through our two 10″ Orion Dobsonian Telescopes, using our home-made (ATM) image intensified eyepieces and my Samsung S7 smart phone hand held at the eyepiece end of the image intensified eyepiece.
The home made image intensified eyepieces were made using old 2nd world war image intensifier tubes purchased from ebay for £50 each a few years ago. They give good views although suffer from significant image distortion towards the edge. However, they represent excellent value for money and provide a quite different way of observing the night sky. Although technically what you see through these image intensified eyepieces is not a direct view of the night sky but instead an electronic image, they give an excellent “through the eyepiece” experience because of where they are located (in the focuser) and the intimate experience of observer and telescope is therefore retained, albeit with a green view!
