About this image

Another double star from the night of the 1st May. With the D90 at prime focus it gives about 0.59 arc seconds per pixel. This image is a crop of the original full frame. I have orientated it with north at the top and west to the right. 54 Leo A is magnitude 4.48, B is 6.29. A couple of field stars are just visible. The separation and position angle of this double is 6.6 arcseconds and 113 degrees respectively. A couple of measurements from this frame gave an average of 6.4 arcseconds and 114 degrees.
