I made a mistake. I attempted to mount a BRC 250 on my Losmandy G-11 for CCD imaging and precise tracking. It can track, but the slightest torque shift is too much, so my mistake is your gain. I have the following Losmandy weights for sale:
11 Pound $55 UPS shipping included
21 Pound $70 UPS shipping included
Both for $120 UPS included.
The weights are in the original boxes and new.
They are for the Losmany G-11, but I believe they will fit the G-8 also. Check to be sure.
