[QUOTE="a33, post: 959100, member: 332642"] It looks like you measured the arm length? Better is measuring at 40% of dish height, as I wrote before (see below, the underlined part). [I](I'm still thinking about a method using three simpler measures of the mounted dish, and then calculating effective focal distance from these three measures, more precise than this 40%-rule of thumb. That may take still a few months, though... :)) [/I] If your 40%-measurement is about 35 cm, then horizontal distance would be about 4,6 cm. If your 40%-measurement is about 40 cm, then horizontal distance would be about 5,3 cm. If, however, your 40%-measurement is indeed about 26,5 cm, then horizontal distance would be about 3,5 cm.
