使用望远镜目视星像评估视宁度时,常用Pickering视宁度等级(Pickering Seeing Scale)判定法,但这个等级并未仔细考虑望远镜的光瞳函数对衍射环的影响.事实上经典的Pickering视宁度等级并不非常适合目前常用的有副镜的折反射望远镜,本文通过数值模拟和解析计算验证了这个问题,并在此基础上对Pickering视宁度等级判定法做了相应的补充. |

The Pickering seeing scale judgment is the most popular method for estimating the seeing by observing the diffraction pattern with a telescope.However,the classical method of the Pickering seeing scale estimation is not a perfect method for estimating the seeing when using the refract-reflection telescope with the second mirror,because the effect of the pupil function of the telescope is ignored in this method.This problem has been testified through the numerical simulation and analytical calculation,so that a corresponding supplement should be done to amend the classical Pickering seeing scale estimation,which is just the main subject in this paper.
