Published in Spring 1987 Zeiss Historica Journal
Author: John Gould
See Page 6 – 7.
The author describes a rare variant of an Asegur telescope which he acquired in near new condition except for the objective lens which had been tampered with to its detriment. He goes on to discuss how he was able to properly align the elements of the triplet objective to bring it back to its intended condition. However, he is an experienced astronomer and repair person and so I would not follow his example unless you can match his skills.
