I hadn't realized when observing y1 and y2 Del that sitting in the same 12mm FOV was another great double, OR Del with HIP 102490 A at Mag 7.45 and HIP 102490 B at Mag 8.25 although they appear nearly similar in magnitude to me
The seperation appears to be about two thirds that of y1 and y2 Del, so about 6 or 7 arcseconds
The colours also appear to be similar, white with perhaps a hint of blue
