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 :
