| 1. | Deferring to historical custom, astronomers, measure the apparent brightness of stars through the magnitude scale, a very confusing way .
按照历史习惯，天文学家用星等标这种容易使人混淆的方法来度量恒星的视亮度。 |
| 2. | The value of the magnitude is increased by about 1 . 5
我们得出星等约增加1 . 5 。 |
| 3. | The color - magnitude relation of disk galaxies
盘状星系的颜色星等关系 |
| 4. | If a value of zero is specified , no magnitude limit will be imposed
如果设定值为0则没有星等限制。 |
| 5. | In the illustration above , the limiting magnitude has been set to 9
在上面的图例中极限星等是9等。 |
| 6. | Upper limit : the upper limit for the magnitude of reference stars
最亮星等极限：参考星的最亮的星等。 |
| 7. | Thus , the apparent magnitude is not an intrinsic property of the star
因此，视星等并不足以显示出恒星的内在特质。 |
| 8. | Absolute bolometric magnitude
绝对热星等 |
| 9. | In the illustration above , the limiting magnitude has been set to 8
在下面的图例中，极限星等是8 ? ?最大可能视场等级的默认星等。 |
| 10. | We can also talk about the absolute magnitudes of objects like star clusters , galaxies , etc
绝对星等的概念可推广至星团星系等。 |
