I pondered for a while on what to do to solve the instability problems caused when using the ETX-125 in a this position. I wanted to keep my 883 tripod because, one I am used to it, and two, tripods are darn expensive! So, being the incurable engineer, I sorted through dozens of ways to fix this problem. The one I finally setteled on came to me while handling my table tripod and the low lattitude balance weight that came with it. I got a longer threaded rod of the same thread pitch as the factory lattitude adjustment screw. To the end of this I fixed a counterweight, which doubles as the knob for lattitude adjustment. The result is a MUCH more stable platform (as stable as the 883 can be). And to clamp the legs, instead of a $45 clamp system Scopetronics uses, I simplu used some small "C" clamps which I covered in key places with felt to avoid scratching the legs. Voila! A home fix for a nagging problem. I have attached a sketch of the fix as my digital camera is not cooperating as of this writing. Clear skies to you, Jim Dishman.
