Using counterweight is advised if you would like to enhance the telescope with additional accessories.
Often, when many accessories are mounted at one time, counterweights are needed to balance the telescope.
Counterweight for balancing when using heavy accessories on Dobson telescopes.
Since Dobson mounts do not have a counterweight bar (as is the case with a parallactic mount, for example),
this weight is contained in a magnetic bag that simply attaches to the outside of the tube of your Dobson telescope.
This allows you to compensate for the use of heavy accessories in order to keep the telescope tube balanced.
The magnetic bag can be attached flexibly to any point on the tube.
