The Sony Alpha A-Mount (SLR/SLT) Astrophotography Adaptor Set enables a Sony Alpha A-Mount (SLR/SLT) Mount camera to be fitted to the eyepiece of a telescope to capture photographs of the night sky. 

This Adaptor Set features a sleeve (make sure to choose your correct eyepiece size from the dropdown menu) adaptor that slides over your chosen eyepiece allowing the Sony Alpha A-Mount T2 Mount, that is supplied in this set, to screw to the sleeve adaptor and allows for the attachment of your Sony Alpha A-Mount (SLR/SLT) camera. This will then allow the image from the eyepiece to be projected to the cameras sensor.

Also included in this Adaptor Set is a set of four Extension Tubes, which can increase the magnification of the image being projected onto your camera. These tubes fit between the Sleeve Adaptor and the T2 Mount. 
  
Please note that since there is no data transfer between the camera and the telescope, focusing and aperture must be set manually.

This set is for eyepiece projection photography not for prime focus.
