Hi,
Before I fixed my telescope tube to the carriage box I had balanced it very carefully with all elements attached - the mirror cell, the finder, the spider and the eyepiece. At the end everything was perfectly balanced indeed, but once I added a barlow, the tube goes slightly down by itself, especially when I try to observe objects that are just above the horizon, like rising Jupiter.
How do you keep balance of the tube of your dobsonian? Do you add some weights on the other end?
Thanks for any tips
