Условие
Observations with telescope
There are 3 binary stars on the given sky chart: β Cyg, δ Lyr, and ε Lyr.
For each of the binaries do the following:
Point the telescope to the binary. Compare the star field seen in telescope’s field of view with three star charts given on a separate sheet. Write down the designations of the binary stars in each blank box under appropriate star chart. Mark North direction on every star chart.


Решение
The official answer sheet identifies the upper field as δ Lyr and the lower-left field as ε Lyr. It marks North with the arrows shown below.

Source discrepancy: the lower-right answer chart is labelled β Lyr in the official key, whereas the question and supplied wide-field chart specify β Cyg. The original answer diagram is preserved without silently correcting its label.
Time limit
The maximum total time for all tasks is 20 minutes.
