55mm f/9.1, 167x
AB: Components A and B separated, whereby the Airy disks slightly overlap. The difference in brightness was well visible.
|
|
55mm f/9.1, 27x
AC: Components A/B and C well separated, but tight. Significant difference in brightness. The fainter C companion appeared slightly orange, the brighter one white-bluish.
|
|
63mm f/13.3, 140x
AB: Components A and B split with almost no space in between. The difference in brightness was visible.
|
|
70mm f/5.7, 133x
AB: Both components A + B clearly split, whereby the diffraction rings where merged together. A very nice view together with component C. I sketched this triplet, which reflects my impression well. Unfortunately, the distance and position angle are not particularly well observed. Also the difference in brightness I didn't noticed during my observation.
|
|
70mm f/5.7, 22x
AC: Well split, relatively close together with significant difference in brightness.
