I visited DSNM a few weeks ago and installed the RST-135 mount. There is no reason not to use counter weights in the remote observatory, but I did not install it to test the mount. That gave me room for my narrow observatory. And I no longer hit my head on the counter weight. :)
The weight of the CCD set is 5kg. The total weight of the mounted equipment is 13 kg. Sorry to the tiny RST-135 mount. LOL
