彗星测光差
Photometry differential of comets
摘要：
这里介绍的结果获得了三个彗星73 P（Schwassmann Wachmann）B的组件B，6P dArrest和C2008 J1（Boattini）。彗星73P于2006年4月被观测到，CCD相机Starlight Express SXL 8连接到牛顿望远镜250 mm的直接焦点，焦距为1200 mm，而6P和C2008 J1曾经被牛顿望远镜观测到，但使用CCD相机Atik 16IC直接聚焦。向CCD照相机添加滤光器光度测定Rc（Schmidt）。对于6P彗星，已经使用了14像素的散焦，这意味着中央假核已经散焦了14像素的FWHM。所用工具的技术数据见表1和表2。
英文摘要：
Here are presented the results obtained with three comets 73P (Schwassmann Wachmann) B the component B, 6P dArrest and C2008 J1 (Boattini). Comet 73P was observed in April 2006 with a CCD camera Starlight Express SXL8 attached to direct focus of a Newton telescope 250 mm, focal length 1200 mm, while the 6P and C2008 J1 were ever observed by telescope Newtonian but with a CCD camera Atik 16IC to direct focus. To the CCD camera was added a filter photometric Rc (Schuler). For 6P comet has been used a defocus of 14 pixels, meaning that the central false nucleus has defocused a FWHM of 14 pixels. The technical data of the tools used are shown in Tables 1 and 2.
