This star is not easy under these conditions, the image is rather agitate, however it is already visible with Plossl 8 mm but I use this high power in order to see better the shape and the structure of the rings. The primary star is fairly bright, it is white with some faint bluish reflexes. The secondary one is decidedly dimmer and its color is warmer than the color of the primary, perhaps yellow with orange hue. The rings of these stars, visible only during the rare quiet moments, are practically in contact. PA estimated about 95 degrees. Interesting double, maybe difficult with smaller instruments. | |||

Very
close doulbe, 1.4"

separate. Had to use 228x. Primary is yellowish-white. |
