Dear Art and all,
Today someone came over with his Kollsman for me to fill. That went just fine. However, upon use we found two new / other issues. Hope someone can help.
1. The image is distorted as if the optics are 'creased' from one corner towards the center. Photo attached although it looks different in real life. Perhaps the pellicle? Strangely, this was not the case before refilling, and all visible optics look fine.
2. On use, the mirror does not seem to move and the direction of view is always straight up.
The two may be interrelated....
Many thanks
Eric
