My scope is now mounted on a permanent pier so I no longer have a use for my scope buggy. The buggy has three leveling bolts and rolls very easily. I embedded steel rods in the ground aligned with the north polar axis so I was able to place the leveling bolts in the rods, level the buggy, and have a pretty accurate polar alignment fairly quickly. I should have had a very good alignment right after leveling and for a while I did but I did find that my Celestron Advanced VX mount polar adjustment knobs tended to loosen when I moved the buggy around so I had to do a fairly quick alignment each time I used it. I have over $300 in the buggy and I will sell it for $200.
