你可能记错了,是十二月这期的。
简单说,AUTOSTAR自动寻星对极轴校正要求不高,但并未说明具体精度。
至于光学质量,适于中低倍大视场深空观测,原话是这样的:
“Ronchi tests showed the optics of both the 8- and 10-inch scopes to be
smooth and free of obvious zones.The 8-inch was slightly undercorrected,
while the 10-inch was a similar amount overcorrected. In neither case
was it enough to noticeably affect the quality of in-focus star images."
"As with all reflectors having relatively large central obstructions,
these Schmidt Newtonians aren't optimized for planetary and double star
observing. Nevertheless, they produced very satisfying views of Venus,
Saturn,and especially the Moon." |
