What computerized go-to mounts make the least amount of noise - normal drive noises, during slewing, beeps or other sounds, etc.? My nightmare neighbor with the industrial class prison-type floodlight on her garage just moved and so far the new neighbors (knock on wood, fingers crossed, prayers and incense for the Gods, etc.) have been willing to turn it off for me. As a result, I have been terrified about doing anything which might annoy them and cause them to turn it back on. My iOptron computerized go-to mount makes quite a bit of noise (especially while slewing between objects) which makes it too loud to use late at night and I have been thinking maybe it's time to invest in a better mount making much less noise.
Are there any relatively quiet go-to mounts? How much noise do they make? Are there any beeps or other sound notifications on them and can those sounds be turned off? I need something capable of handling a TOA-130 and maybe even a lighter 6" refractor (perhaps a TEC 140). I am looking for something I can connect to a tablet or laptop computer running Starry Night Pro or Sky Safari Pro. I was thinking about the Astro-Physics Mach1 or the Takahashi EM-200. If I could find one, maybe even an older AP mount like a 600, 900, etc.
I would even be willing to give up the computerized go-to and slewing as long as I could add digital setting circles and use it as a manual push-to mount with a basic drive. I just don't want unhappy neighbors and I am willing to make sacrifices.
Okay wonderful people, what are some of my mount options?
