Near Gamma-Leonis

Two images taken about 30 minutes apart

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.
