Just to probe the point, I then took the OTA with all the cables and optical train and mounted the whole rig in my 3-year-old iOptron CEM40 EC in the same spot, using the same ASI Air+ where moments before the AM5N had been tested.
I have attached a couple of subs with narrow band filters of the Lion’s Nebula, 300 secs, -10C (8b, 9b) and the performance over 200 secs of the optical setup using the iOptron mount (7b). I believe this is fairly strong suggestion that there is something wrong with the AM5N, however, I am willing to be convinced otherwise.
Hopefully, the results will demonstrate that I am not totally inept in this hobby
