What direction should a telescope point?
What direction should a telescope point?
In the northern hemisphere the best direction to align the telescope is so it has its best view to the south. The reason for this is to do with the tilt of Earth’s axis of rotation. Earth is tilted approximately 23.5° to the plane of the solar system and we in the UK are located towards the north of the planet.

Where does James Webb Space Telescope orbit the Sun?
Webb will orbit the sun 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2. (Note that these graphics are not to scale.)
Why is the telescope out at the second Lagrange point?
To have the sunshield be effective protection (it gives the telescope the equivalent of SPF one million sunscreen) against the light and heat of the Sun/Earth/Moon, these bodies all have to be located in the same direction. This is why the telescope will be out at the second Lagrange point. What is L2?
Which is the next deployment of a telescope?
The next deployment is the telescope in which the telescope and the spacecraft bus move apart from each other by about 2 meters when the deployable tower assembly extends. The full sunshield deployment with unfolding and tensioning of the membranes can then be initiated.
Where is the SALT telescope in South Africa?
Like HET, SALT also has a fixed-angle design that has complicated observations since it began operation in 2005. But the instrument can still view about 70 percent of the sky observable from Sutherland, South Africa.
