论文摘要
我们介绍了Cerberus的初步设计，Cerberus是意大利热那亚山脉Ligurian山脉的Alt-az，80cm Oarpaf望远镜的新科学仪器。 Cerberus将在Nasmyth焦点下提供三个焦点站，允许：成像和光度法，标准Johnson-Cousins Ubvri+Ha+Free Fire Filters，一个轴向引导摄像头和一个尖端倾斜镜头，用于图像稳定性高达10Hz；由于提供了1200升/毫米Grism的LHIRES III光谱仪，在R 5900处的长狭缝光谱法；使用光纤的Flechas光谱仪，在R 9300处的Échelle光谱。
We present the preliminary design of Cerberus, a new scientific instrument for the alt-az, 80cm OARPAF telescope in the Ligurian mountains above Genoa, Italy. Cerberus will provide three focal stations at the Nasmyth focus, allowing: imaging and photometry with standard Johnson-Cousins UBVRI+Ha+Free filters, an on-axis guiding camera, and a tip-tilt lens for image stabilization up to 10Hz; long slit spectroscopy at R 5900 thanks to a LHIRES III spectrograph provided with a 1200l/mm grism; échelle spectroscopy at R 9300 using a FLECHAS spectrograph with optical fiber.
