You commented: No cross hairs to center bubble!! No, because the instrument is tilt invarient. If you tilt it, the bubble follows the image, so you do not need cross hairs...
If I tilt my A-12, the bubble will, of course, move opposite the tilt. AND the body will go opposite that. The bubble doesn't follow the image at all. What am I missing? It would be wonderful if the A-12 was tilt invarient. Perhaps I'm using it wrong or something in the optics is missing.
