Pressumably, they didn't have the high-precision devices required to measure those angles. You must consider that we are talking about extremely small angles - even the closest star has a parallax of less than one arc-second (1/3600 of a degree).

What have Astronomers have been unable to prove that what exist?
'Dark matter' and 'dark energy' have not been observed or proven yet.
Astronomers have been unable to prove it exists?
Astronomers are unable to prove the existence of dark matter & dark energy.In fact astronomers have not yet proved most astronomical effects. Worm holes, black holes, or even the big bang. But proof in theories is almost impossible. The longer a theory stays intact is a sign of it's "proof" but some "sane" theories have been proven to be incorrect - "Einsteins biggest blunder".No scientist will say they have proved anything "astronomical" as it is almost impossible to prove anything without physical interaction.It's a bit like saying "I can prove that dogs live in the next street" based on only hearing their barks and not actually going there.
What is astronomers have been unable to prove that it exists?
There are several speculative ideas in astronomy, which can't currently be proved - nor completely disproved. Some of these include wormholes; parallel universes; the possibility of time travel and faster-than-light travel.
Why is the light unable to reach the screen?
Explain why the light is unable to reach the screen
Which planet has a moon called charon?
Charon is so far away and so small that astronomers are unable to see it from Earth. It is therefore unsure whether Charon has craters but it is likely as every other planet and moon in the solar system has been bombarded by meteors in the past.
Why were ancient people unable to detect stellar parallax?
they couldn't measure small angles

18 weeks pregnant but ultrasound unable to detect baby?
its not bad dnt worry but its just to early
If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
Your computer is unable to detect pen drive?
There are several reasons why a computer is unable to detect a pen drive. One common reason is that the computer does now know what drive letter to assign to the memory stick. One quick fix is to change the drive letter in the administrative tools of the control panel.
How did Sirius Black escape from Azakaban?
He was an unregistered animagus. He escaped by turning himself into his animal form which the Dementors were unable to detect.
What taste are cats unable to detect?
Studies suggest that cats can not detect sweetness. In cases where a cat chooses to eat something sweet, like ice cream, scientists hypothesize that this is because of the temperature ans texture of the ice cream, not the flavor.
You are unable to have a pap smear what else can be done to detect cervical cancer?
You can do HPV genotyping to know high risk and low risk type of HPV.
Why are wireless technologies like WiFi and 3G unable to reuse the Ethernet data link layer?
Wired Ethernet can physically detect collisions, WIFI can't.
