I needed another counterweight for my Ioptron Skyguider Pro. I have the William Optics counterweight extension bar but noticed that it makes the mount more sensitive to wind and vibrations with the one counterweight hanging so far out. Having two weights closer to the RA axis seems to be more stable; I've been rejecting fewer subs when processing my images.
And thanks for the Gummy Bears Astroshop, a tasty bonus!
