During medieval Islamic golden age astrometry, which effect complicated accurate star position measurements using astronomical observatories?

💡 Explanation

When starlight enters Earth's atmosphere, atmospheric refraction occurs because air density varies with altitude, causing light to bend and distorting observed star positions, particularly low on the horizon. Therefore atmospheric refraction results, rather than aberration or gear slippage, which were limitations of later telescope technology.
