Would you mind creating a post on your process to correct the objective?
Kasmos posted the info to which I was going to link. But, if you need/want more, there are several threads about it. I don't want to go too far down this road, in deference to the thread topic, but can PM a link or two if you'd like.
In a nutshell, besides the diagram that Kasmos posted, with an properly ordered/assembled air-spaced doublet, you will see Newton Rings. If you don't see them, the elements are improperly arranged. I did not see them. I have disassembled quite a few objective cells, but I don't believe I have ever actually found one that was previously put together wrong. So, I had to review stuff I had read on here. Some of the threads I read to figure it out:
There are quite a few different threads besides these. Search "crown and flint orientation" or some such. I searched specifically the "Classics" forum.
To keep with the thread, here is the mess I cobbled together for my "tiny" Swift. I wanted to be able to mount it on my GP and try some cell phone pics. It looks ugly, because it is, but it WORKED. Not posting because I am proud, but because I have no pride. LOL. I just wish the seeing had been as great as the seeing the night before.
