This image is a complilation of shots with my DX camera and FX camera with three different optics; the first is a 120 mm f/5 achromat, the second a 150 mm f/5 achromat, and the third a 500 mm f/8 reflex lens.  My goal was just to see the different image scales I could expect and therefore which one would be optimal for the eclipse in April.

Pay no attention to the fact that the middle images are badly out of focus; that telescope doesn't have enough back focus for my cameras, so an extension tube should fix that.
