Subject: dismanteling the ETX70 scope Sent: Saturday, May 26, 2007 04:28:19 From: firstname.lastname@example.org (email@example.com) start with going to "astro76.mypunbb.com/viewtopic.php?id=3958", which brings you to the Forum in general, choose " desmontando el ETX 70 por Piter", thats the series of about 50 fotos I followed to dismantle the scope. Once I get things OK with the decl.motor, i'll send you more details. Tell me if you got this right. andrew.
starting from foto n 21 from the link I send you , I unsrewed the 3 bolts holding the dec. arm with mecanism and electronics. After having undone the arm protection,( 5 screws), I loosened the printed circuit, controlled the dec and azimuth motors, which I found both OK so the problem must be in the circuit board itself, which I can't check because off my lack of knowledge in electronics. I don't have the drawing of the circuitery anyway. I cleaned the lot, I did not find any grease on the circuit board, and little on the mecanism. To asemble again, follow the explanations given in the link I send you. By the way, I fell in my shack, dropping the scope and tripod to the hard ground, ..I was lucky, no harm to lenses, only the plastic eyepieceholder got bend and I had to straighten it out again using a pair of players. If any information is unclear or missing I will come back on it OK ?. Thanks a lot. andrewMike here: I'm sure this will be helpful to others.
I have a "terestrian scope"for the moment, until I get to the problem seriously. The printed circuit on my scope says " ETX 60- C-2005 Meade- 15-6855-00 Rev 6. I don't think this is any worth to otrhers!!. Yes the fall was a lucky one, I got away with it with some black spots and some blood too. but not serouisly. Thanks for all. andrew.
