This ES Twilight II has several modifications from original that improve it's function and usefulness.

The mount is in excellent condition with minimal signs of use. Includes the mount itself, the pier extension and the tripod.

The mods consist of:

1) Machined the altitude shaft for two stop knobs to prevent over rotation past the horizon or zenith. They can easily be disengaged if needed. (Photo shows the two knurled knobs next to the altitude friction knob)

2) Improved fit of the azimuth bearing by machining, so movement is smoother, especially in the cold.

3) Two extra bolts added to the end of each dovetail clamp to strengthen it.

4) Two 3/8" tapped holes allowing optional stainless counterweight shafts to be attached.

These mods were all done in my professional machine shop.

NOTE: Optional dovetail mounting plates for binoculars (the bare aluminum parts in the 4th photo) and two counterweight shafts are extra. Please ask if interested and I can price them fairly.
