  1. Hi Richard,

    Yes, I am using an Orion Short Tube 80mm f/5 guidescope with an Orion Starshoot guide camera.

    I am not using a reducer because the new ED120 I am using has a nice wide field and is giving me plenty of objects to shoot. I did use a reducer on my old LX-90 and I haven’t ruled out using one on this scope at some future time.

    The ED120 came with its own field flattener which I have yet to use.
