古德说这些图像由大熊湖天文台的1.6米通光孔径离轴新型太阳天文望远镜拍摄。

Goode said that the images were achieved with the 1.6 m clear aperture, off-axis New Solar Telescope (NST) at BBSO.

孔径越大，它收集的光越多，成像的亮度和清晰度就越好。

The larger the aperture, the more light it collects and the brighter and clearer the image will be.

这不是星星自身的光环，而是由于望远镜的圆形孔径光阑以及光的物理特性造成的。

This is not the star's disk you are seeing but the effect of having a circular aperture in your telescope and due to the nature of light.
