Бележка

Telescope: 150/750 Newton

Eyepieces: 25 mm, 10 mm, Barlow lens: 2x

Note:

  • Telescope is already polar aligned.
  • In case of bad sky conditions at low altitudes, task 1 and 2 will be replaced by alternative tasks 1 and 2 (see page 3). In this situation, the telescope assistant will cross out Tasks 1 and 2.
  • You have to use 25 mm eyepiece for tasks 1, 3 and 4.
  • For these tasks, if you finish before the allotted time, you must keep tracking the object with the telescope till the end of allotted time. The telescope assistant will check the object only at the end of the allotted time.
  • For task 2, we recommend using 10 mm eyepiece and Barlow 2x.

Условие

available time: 10 minutes, total: 10 points

Find the planetary nebula M57 (in constellation Lyra), and put it in the centre of the field of view in the main scope.

The star chart in the answer sheet shows a part of constellation Lyra. In this chart, draw the FOV circle around M57 as accurately as possible.

If you cannot find M57, the assistant will help you, but only after 5 minutes. In this case you will lose the marks for pointing to the object.
