High-resolution observations of polar crown and high-latitude filaments are scarce. We present a unique sample of such filaments observed in high-resolution H\(\upalpha \) narrow-band filtergrams and broad-band images, which were obtained with a new fast camera system at the Vacuum Tower Telescope (VTT), Tenerife, Spain. The Chromospheric Telescope (ChroTel) provided full-disk context observations in H\(\upalpha\), Ca ii K, and He i 10830 Å. The Helioseismic and Magnetic Imager (HMI) and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) provided line-of-sight magnetograms and ultraviolet (UV) 1700 Å filtergrams, respectively. We study filigree in the vicinity of polar crown and high-latitude filaments and relate their locations to magnetic concentrations at the filaments’ footpoints. Bright points are a well studied phenomenon in the photosphere at low latitudes, but they were not yet studied in the quiet network close to the poles. We examine size, area, and eccentricity of bright points and find that their morphology is very similar to their counterparts at lower latitudes, but their sizes and areas are larger. Bright points at the footpoints of polar crown filaments are preferentially located at stronger magnetic flux concentrations, which are related to bright regions at the border of supergranules as observed in UV filtergrams. Examining the evolution of bright points on three consecutive days reveals that their amount increases while the filament decays, which indicates they impact the equilibrium of the cool plasma contained in filaments.

极地冠和高纬度细丝的高分辨率观测很少。我们提供了在高分辨率H \（\ upalpha \）窄带滤光片和宽带图像中观察到的这种细丝的独特样品，这些样品是在特内里费岛真空塔望远镜（VTT）上使用新型快速相机系统获得的，西班牙。色球望远镜（ChroTel）在H \（\ upalpha \），Ca  ii  K和He  i中提供了全磁盘上下文观测 10830Å。太阳动力天文台（SDO）上的日震和磁成像仪（HMI）和大气成像组件（AIA）分别提供了视线磁图和紫外线（UV）1700Å滤镜。我们研究了极冠和高纬度细丝附近的花丝，并将它们的位置与细丝脚上的磁集中联系起来。在低纬度的光球中，亮点是一种经过充分研究的现象，但尚未在两极附近的安静网络中对其进行研究。我们检查了亮点的大小，面积和偏心率，发现它们的形态与低纬度地区的同类非常相似，但是它们的大小和面积更大。极性冠状灯丝脚部的亮点优先位于较强的磁通量浓度处，这与在UV滤镜中观察到的超颗粒边界处的明亮区域有关。检查连续三天亮点的演变过程，发现它们的数量在灯丝衰减的同时增加，这表明它们影响灯丝中所含冷等离子体的平衡。
