AstraLux是Calar Alto 2.2米望远镜的幸运成像相机,基于电子倍增高速CCD。通过在几千个短曝光帧中选择最好的1-10%,AstraLux在SDSS i‘和z’滤光片中提供了近乎衍射限制的成像能力,视场范围为24×24角秒。只要有可能,只要选择市售部件,就可以在短时间内以相对较低的成本制造仪器。介绍了该仪器的设计、数据简化流程,并对其性能和特点进行了总结。
AstraLux is the Lucky Imaging camera for the Calar Alto 2.2-m telescope, based on an electron-multiplying high speed CCD. By selecting only the best 1-10% of several thousand short exposure frames, AstraLux provides nearly diffraction limited imaging capabilities in the SDSS i' and z' filters over a field of view of 24×24 arcseconds. By choosing commercially available components wherever possible, the instrument could be built in short time and at comparably low cost. We present the instrument design, the data reduction pipeline, and summarise the performance and characteristics.
