Po­lar Finder

Sky at Night Magazine - - OCTOBER / FIRST LIGHT -

Equa­to­rial mounts re­quire po­lar align­ment to avoid star trails and field ro­ta­tion dur­ing long ex­po­sures. The MiniTrack is sup­plied with a very sim­ple po­lar finder com­pris­ing an 8mm sight­ing tube that fits into a clip on the end of the drive unit. Vis­ually align­ing with Po­laris through this tube achieves an ap­prox­i­mate po­lar align­ment, which works well enough.
