摘要:

本文旨在纪念Victor Afanasiev博士及其巨大的遗产。该报告重点介绍了在SAO RAS的1米蔡司-1000望远镜上测试的两种新仪器的能力:斯托克斯偏振计(StoP)和MAGIC焦减速器。这些仪器是为研究活动星系核(AGN)而优化的,系统地,这些仪器适用于各种小型望远镜任务。对于直接图像,StoP和MAGIC的视场分别为6'和13'。StoP设备允许使用双沃拉斯顿棱镜进行光度观测和偏振观测;光谱模式被添加到MAGIC。对于14等的星状目标,在视宁度为1”的中波段滤光片中,总曝光时间为20分钟,测光精度优于0.01等,偏振精度优于0.6%。用MAGIC中的体相位全息光栅获得的可用光谱范围为4000- 7200 AA,色散为2A/px。StoP和MAGIC于2020年首次亮相,并在蔡司-1000的测试模式下使用。该报告讨论了作者用新仪器获得的第一批结果,以及进一步的前景

英文摘要:

This paper is devoted to the memory of Dr. Victor Afanasiev and his immense legacy. The report highlights the capabilities of two new instruments tested at the 1-meter Zeiss-1000 telescope of SAO RAS: the Stokes Polarimeter (StoP) and the MAGIC focal reducer. Optimized for the study of active galactic nuclei (AGN), methodically, these instruments are suitable for a wide range of small telescope tasks. The fields of view of StoP and MAGIC are 6' and 13' for direct images, respectively. The StoP device allows one to conduct photometric observations and polarimetric ones with a double Wollaston prism; the spectral mode was added to MAGIC. For a starlike target up to 14 mag in medium-band filters with a seeing of 1" for 20 minutes of total exposure, the photometry accuracy is better than 0.01 mag and the polarization accuracy is better than 0.6%. The available spectral range obtained with the volume phase holographic grating in MAGIC is 4000-7200AA with a dispersion of 2A/px. StoP and MAGIC received the first light in 2020 and are used in test mode at the Zeiss-1000. The report discusses the first results obtained by the authors with new instruments, as well as further prospects
