Superb Finish

William Optics polished anodized finish.
All internal surfaces threaded and blackened to prevent reflections.

Easy to Use: Will accept any standard 48mm T-ring for your camera.

Suitable for: GT71, GT81, Z81, Z103, Z126 (GT = Gran Turismo, Z = ZenithStar)

You have to adjust the flattener to your telescope:
