The dome was my father in law's one. I don't know where he bought it 20 years ago. I just moved it from Banon (Alpes de Haute Provence) to Pierrevert (the place where I live most of the time know. So my (future) observatory is located near Pierrevert - itself near Manosque. I 'll send you photos when it is finished (a few weeks I hope )

You are right, but a first step is achieved !

Thank you very much to both of you ! As pointed by Lucas, there is one error in each drawing : the north pole axis is pointing south in a) (!!) and the mentions N and S at the top of the drawing b are wrong in drawing b. Depending what you look in each drawing, you might consider either a or b could be valid (or wrong!) Now that those two errors are corrected, it is interesting to notice that the two solutions are hopefully identical, one seen from the East side and the other from the West side And the center of the pilar must be offset 13 cm to the South from the dome center !! I will sleep much better tonight Thanks again Configurations ciblesV2.pdf

Hi, I have just ordered an ASA DDM85 Premium mount. Building the observatory, I have to position the pier basement relative to the center of the observatory. Asking details and support to the vendor, he sent me a drawing of the target configuration (configuration A) I don't understand this drawing because the RA axis is not aligned with the celestial pole axis, and it supposes that the RA axis is on the upper part of the mount. To my understanding, the configuration of the mount should be configuration B, with the RA axis aligned with polar axis After several exchanges, the vendor still confirms that the correct mounting must be as in A Is somebody able to decide who is right and why Here are the two configurations : Configurations cibles.pdf
