Very well made accessory. It mounted to the rail with no issues and I was able to balance the 3rd axis on my 8″ Edge HD (the weight ended up at the very end of the threaded rod). My scope was very much out of balance on the 3rd axis even though it was perfectly balanced on the Dec and RA axis. My OAG guiding error was reduced from an average of about 1.5 arc seconds to less than 1 arc second on average. Very pleased with the improvement.
