Thank you Tony, there is a little bit of weight added,depends on size of motors, and the box to cover the motor is made from foam card so no weight there 🙂  As far as vibration is concerned I haven’t witnessed any as such. I do know there is a very slight shift within the collimating lens when using motor but that can be sorted by adjustment of the original lock screws (found this out after my posting the info above).  I always thought I had focus on neon lines sharp when I set it up manually,but it’s surprising how much sharper the lines get when I  can just nudge the rotation,certainly makes a difference.
