Re the above, any clarification, advice, suggestions would be appreciated.
1. I have an Astra IIIB, which came with a 3.5 x 40mm straight scope. No problems with it, other than the sometimes questionable nature of my sextant technique.
2. I recently purchased a 7 X 35 mm monocular. There is a dimensional difference between the mounting brackets on the two scopes which if you will bear with me on a semantic point, I will describe as "two tined forks". The length dimension of the monocular's fork is, as I measured it, 5/16" longer than the mounting fork on he straight scope.
3. How should one position the monocular on the sextant so as to get a proper horizon image, respecting the dimensional difference betwween the mounting forks?
Thanks.
Alan
