I’ve owned a Eq6-r for several years. Last year I decided to buy a made Acf 12” from a friend of mine.
At first it seemed to be a good combination. I took several good pictures of the moon and the main planets. The tracking was smooth and it seemed that the mount could cope with the weight of the telescope easily.
But problems began first time I took the telescope to a dark location and I used the goto to find objects.
After half and hour the mount stopped working and I had to switch it off and on. It worked for a while until I experienced again the same problem
Back at home I tried the mount with one of my refractors ( apm 130 f/9.25, 9 kilos and very long) and it worked without any issues. I switched the telescopes and set up the 12” and after some minutes the problems returned.
i really don’t Know what the problem was but it was related to the weight of the meade so I had to sell it.
I’ve used the mount with a 9.25 edge hd and several big refractors ( between 130 and 140 mm) and I’ve never experienced problems with another telescope.
So I wouldn’t recommend this set up at all
