Gamma Leonis is a binary star. It's two components are separated by 4
arcseconds. I took some short 0.1 second exposures, but even in these images
Gamma Leonis saturated the CCD chip. However, applying a Richard-Lucy
deconvolution followed by a logarthmic stretch, it is possible to see
elongation in the binary. Click the image to see the full frame with
Vesta.
