Hi Can't see any info on how much your ACDS costs. Does it come already supplied with your new scopes or is that an optional extra? Thanks

We don't have a final price yet, but figure around $1500. We have been way to busy lately getting scope orders finished to even think about the ACDS. The hardware is done, we just need to get the installation software automated enough where we don't have to spend an hour on the phone with each customer. Maybe late this year we can wrap that project up.

Looks like an old thread, but I'll try to bring it back to life :) There's very little information about ACDS on your website - can you shed a bit more light on it? How does it work? Does it rely on ServoCAT motors, or it's a standalone system? Thanks in advance!

It is a standalone system. It works just like the noise canceling system in a luxury automobile or headphones. The ACDS knows what normal noises are with the scope; for example the sound of the Servocat tracking or slewing. Random noises like the 17hz sound of wind blowing on the scope, are canceled by the microprocessor creating the exact opposite waveform. If you tap the scope, the image remains unmoved. If someone near you jumps off the last step of their ladder, your high power image does not turn into a "-" sign. Now of course you are going to ask if you need this option at all. A year ago some guys who do vibration analysis for the auto companies tested our scopes compared to a dozen other brands. Our damping performance at the tested frequencies was already several times lower. So we are not going to say that you absolutely need the ACDS, but it will be an interesting option when it becomes available.
