iv'e purchased a 16" lightbridge for astro camps and viewing away from home and my pod.have been struggling with setting circles and found richard from victoria here on iis who had progammes of setting circles that he could make to your measurements and wow he does a fantastic job.!!!!!!!
i did some changes and thought some of you here may want to use them.instead of paper i used drafting film 100 gsm ppc like a thin plastic.still had it laminated but made it around 14mm smaller then the scope base they cut the laminate 5mm larger then the setting circle so they could seal the edge that way no dew etc could get between the laminate.ive taken photos to show the setting circle and what it's like compared to laminate paper..
