bosun21 Posted May 15 Share Posted May 15 You want to make a cover for the scope from thick card and cut a circle that will fit inside one of the quadrants between the spider veins. Cover the circle with solar film and that is more than enough for your 14" dobsonian. 2 Link to comment Share on other sites More sharing options...
Stephen196360 Posted May 17 Author Share Posted May 17 Hiya guys I've made a 1 quarter sun mask But for the life of me I can't see how that Works Though I've not tried it yet.....lol I've a small reflecting telescope with a small sun filter in the middle and it seems to work fine So maybe I just need a little faith in what I've got Will keep you posted Regards sid Link to comment Share on other sites More sharing options...
Peter Drew Posted May 17 Share Posted May 17 This sounds a little odd, do you have an image of the set-up? 🙂 Link to comment Share on other sites More sharing options...
