Received new lens cell from Northgroup yesterday. A big thanks to Gilman on this. They bent over backwards in helping me.
Managed just a little peek at the sky last night before clouds rolled in. The air was quite turbulent so tests are taken as a grain of salt. However it looks very encouraging. Acid test..Venus. Small amount of fringing...60% less than previous. This (fringe) is expected given Venus is so bright at the moment.
Moon shots came up quite good and some focusing tests good as well. Here is a small de-focused test on Beta Centauri..which is a very blue star. The main thing is that fringing is pretty much concentric with the star.
I tried to snap the ptolemy cluster but clouds beat me and I didn't get focus accurately..so maybe next time. There is still some fringing but as I said it's concentric with the stars which is encouraging.
