I asked the BGO robot to image the double star 39 Leo for me. It is near the top-right of this image.
Luminance only, 3 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.
I wanted to revisit this double, aka SAO 81270, as I had not successfully split it back in May 2014. Was it because the noted magnitudes are very different (5.8 vs 11.4)? Or something else.
Certainly it is curious. There is no bright star to the north-east of the primary! But there is a noticeable bump on the primary at the north-west! That's a significant change. SkyTools does not show this as a binary. I'll have to do some research...
