Abstract

The 152-cm telescope of the Cerro Tololo Inter-American Observatory in Chile is to be made to a design producing images that are free of the usual Ritchey-Chrétien astigmatism. A 38-cm diam fused-quartz correcting plate is used to give a field diameter of 1. degrees 5, over which images are less than 0.5 see of arc in diameter.

摘要

位于智利托洛洛山美洲天文台的152厘米望远镜将按照一种设计制造，这种设计能产生没有常见的里奇-克莱琴像散的图像。一块直径38厘米的熔石英校正板用于提供1.5度的视场直径，在这个视场直径范围内，图像的直径小于0.5角秒。
