Mees CCD（MCCD）仪器是一种成像光谱设备，它使用25厘米日冕望远镜和位于毛伊岛哈雷阿卡拉的Mees太阳天文台（MSO）的3.0米Coudé摄谱仪。该仪器的分辨率高达R 200 000，通量从λ3934 λ（Caii K）到λ 10 000 λ。一个快速引导的主动反射镜在观测过程中稳定了图像。快速写入磁带存储系统允许以256 kbytes s-1的速度记录观测值。目前，MCCD被用于λ6563 λ（Hα）太阳耀斑的成像光谱学和本影振荡的速度测量;未来的计划包括活动区日冕的发射线研究和太阳振荡的光球研究。
The Mees CCD (MCCD) instrument is an imaging spectroscopy device which uses the 25 cm coronagraph telescope and the 3.0 m Coudé spectrograph at Mees Solar Observatory (MSO) on Haleakala, Maui. The instrument works with resolving power up to R ≈ 200 000 with significant throughput from λ3934 Å (Caii K) to λ ≈ 10 000 Å. A fast guiding active mirror stabilizes the image during observations. A rapidly writing magnetic tape storage system allows observations to be recorded at 256 kbytes s−1. Currently, the MCCD is used for imaging spectroscopy of solar flares at λ6563 Å (Hα), and velocity measurements of umbral oscillations; future plans include emission line studies of active region coronae, and photospheric studies of solar oscillations.
