| Placement Of Mirror
Forum List | Follow Ups | Post Message | Back to Thread Topics Posted by Jim/">Jim on January 31, 1999 22:27:15 UTC |
Is there an exact measurment to use when placing the primary mirror inside the tube? I have a 12ID tube and (will have) a 10" mirror f 5.6 My tube is 61" long and if the mirror will be correct when I receive it, the focal length should be 56". Can I attach the primary with the bottom flush with the bottom of the tube, or is there a specific procedure to follow? Thanks for any help Jim |
