Coronado – Canon Nosepiece


I made a nosepiece to mate my Canon 60Da to my Coronado Hα solar telescope. The lens and it’s mounting hardware were repurposed from a Meade #126 Barlow. With the nosepiece inserted into the Coronado, the first surface of the lens sits inside the barrel at a depth of 26.5mm. The nosepiece has a flange that spaces the Zhummel Canon EOS ring 2mm away from the end of the Coronado barrel. The nosepiece was machined from an existing 1.25″ t-ring nosepiece. The modifications were made to create the desired focal lengths between optical elements and to allow for the press fit of the Meade lens. The result creates a large image of the solar disk that fits on the sensor.
