We do NOT recommend adding length to the counterweight rod because of the whip affect -- it becomes a diminishing return. You get balance, but you also get longer waves of vibration that don't dampen out as fast.

The only real option is to add another counterweight.

Be aware that ExploreStars is recommended for visual, not astrophotography. Certainly it will get your started, but soon you need to explore going wired to a computer using ASCOM and the Planetarium program of your choice.

Subject: [ESPMC-Eight] iEXOS 100 Weight Distribution Question


The new mount performed flawlessly last night at Joshua Tree NP (Peter couldn’t make it), but I still have to spend much more time with it in the daytime to better understand how the ExploreStars commands work to adjust the scope. I had some difficulties manually moving the right directions or amounts for different celestial objects being viewed in my 25mm eyepiece.

But with my William Optics Z61 scope & red dot finder, ZWO guiding scope/camera & a focuser motor, Fuji mirrorless camera, field flattener & T-ring adapter, the total payload is exactly 8.3lbs. The two balance weights, at another 4.4lbs, don’t quite balance this. At already 12.7lbs, I really don’t want to have to add another 2.2lbs with a third balance weight. Is there any kind of extension rod I can add to the existing one to achieve balance with less added weight? Or how far would I have to move the payload with a longer vixen dovetail bar to get it in balance? My current WO one is 110mm long (weighing just over 8oz), but they also make one that is 220mm. What would you recommend?
