It's not obvious from the photo below, but at high altitudes the bungee actually pulls the front of the telescope "down" to counteract the weight of the finders, focuser and eyepiece(s) hanging over the back of the tube. Using Pace Weights, you control the size of your weight increments and how often to add them, and Pace Weights work with different types of metal weight training equipment, so you can use the technique for all your weight training exercises.

Pace Weights are sold in complete sets of 9 or 18 one-half pound weights and can be purchased with or without a convenient carrying case.With the ease and convenience of magnetic attachment, half-pound Pace Weights let you add weight training resistance without lowering repetitions. Pace Weights let you “pace” your weight increments, if you choose, to match the fastest rate at which your muscles can grow, so you can build your muscles faster and achieve your development goals sooner. I also love the fact the weight(s) can be moved quickly and easily up and down to achieve perfect balance. I've recently got a few heavier accessories for my 150p skywatcher dob: a 2" 70 degrees eyepiece and upgraded the finderscope from a 6x30 to a 9x50. Pace Weights can keep you motivated by eliminating sticking points and letting you experience strength gains on a frequent and regular basis.

That the key not only for its rock-solid stability but also to the perfect fluidity of rocking forward and backward motion.

Was doing mainly planetary observing at low altitudes that previously tended to cause the scope to slowly tilt downwards.
