If your pixel scale is much larger than the values quoted above, then the quality of the astrometry will suffer. If your pixel scale is too low for your local setup, then the signal-to-noise of the images may be low as each image is spread over a large number of pixels.

如果你的像素分辨率比上面要求大很多的话，那么可能导致天文测量的测量品质下降，但如果你的像素分辨率比上面要求的小很多，则会导致图片的信噪比下降，因为每个目标占据了过多的像素。

I recommend Canon EOS DSLR cameras for long-exposure astrophotography because of their proven performance, low noise and ease of use in working with true raw files.

我推荐佳能EOS数码单反用于长时间曝光的天文摄影，因为它们已被验证的表现，低噪声与真正RAW文件（注：这点是针对尼康的RAW做了手脚来说的）的易用性。

S data, and get the parameter estimate of ARMA noise by Hannan-Rissanen s linear procedure, then the estimate is of strong consistency and is of asymptotic normal efficiency for Gaussian series.
