IOAA 2019, Нощни наблюдения и планетариум — Задача 1 (алт.). TASK 1/ALTERNATIVE: FINDERSCOPE ALIGNMENT

OBSERVATIONAL ROUND – QUESTION SHEET · 5 т.

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.
  • For task 5, you are not allowed to use the telescope.
PLANETARIUM ROUND – ANSWER SHEET

3 projected images with questions. Each part is 15 minutes long. Total time: 45 minutes.

Условие

available time: 5 minutes

The finderscope is NOT aligned at the beginning. Point the telescope to Altair (α Aql) and align the finderscope parallel to the main tube.

If the alignment is not satisfactory, the telescope assistant will correct it – and you receive only partial or no points.

Решение

Внимание: Непълно решение
