Sent: Friday, August 26, 2011 17:50:18 From: mamonett@comcast.net (mamonett@comcast.net) After a few months of trying to get true north alignment with my etx125 and a linsatic compass it finally dawned on me; forgive me if this procedure has appeared on your site before. First of all you MUST KNOW your magnetic deviation from true north and your finder scope or red dot must be spot on at infinity. Next a attach a short section of 1.25 inch O.D. chrome drain pipe from a plumping store about 1/2 to 3/4 inches long to the bottom of the linsatic compass, this will fit nicely into the eyepiece holder. I used JB WELD. Set the compass with the 1.25 O.D. inch drain pipe into eyepiece holder. Next align the compass to the same object as your finder or red dot and tighten the "screw"; now you will have the compass aligned to your "tube". Don't forget to account magnetic deviation from true north. Now you can use the linsatic compass to find true north and the scope will follow. The above takes for granted an understanding of how to use a linatic compass. And: Here are a couple of photos, as you can see I feed the birds. And I might caution someone who is unfamiliar using a compass; iron objects affect the accuracy of compasses, such as the nails in the deck where I took the pictures. |
