AMount Palomar dHubble Space Telescope Why does HST generally still outperform the ground-based 5-m telescope? The resolving power of the Mount Palomar 5-m telescope has a higher value than that of HST, and telescopes with higher values for resolving power can not distinguish objects as well as telescopes with lower values for resolving power. Earth's atmosphere affects visibility for the Mount Palomar 5-m telescope and limits resolving power to about 0.5 seconds of arc. HST is not affected by distortion due to the atmosphere. The resolving power of the Mount Palomar 5-m telescope has a lower value than that of HST, and telescopes with lower values for resolving power can not distinguish objects as well as telescopes with higher values for resolving power. HST is in orbit around the Earth, and so it is closer to the stars than the Mount Palomar 5-m telescope. By being…arrow_forward
