Blue Mountain Vista Observatory New RInggold PA
NGC 4565 is a mag 10.4 (visual) an edge-on spiral galaxy in Coma Berenices It is estimated at 30-50
million light years distance. It was discovered by William Herschel in 1785. This was reported as John
Dobson's favorite object in the sky and my image is dedicated to his memory.
This image was taken with a prototype of an on-axis guider, which has a mirror that reflects the visual
image light to the camera at a 90 degree angle, while allowing IR light to pass through to the inline
guider. It works well and gives a very good FOV for the guide camera.
