| Converting A Camera Telephoto Lens

Hi, I have a 300mm f4 apochromatic Canon telephoto lens, my new pride and joy. And, I will soon be getting a 2x tele converter that will make it 600mm f8. I would like to buy an an 90 degree standard eyepiece holder that I can attach to this lens so it can do double duty as a modest power 75 mm apeture (with top notch optics) astronomy telescope. The only adapter I have been able to find is a Kenko telephoto-spotting scope adaptor. This Adaptor is straight through and has a built in roof prism and eyepiece- not quite what I am looking for. Thank you for any help you can provide. Keith |
