We had our monthly meeting (astronomy club) Wed. nite, I saw Jupiter through our 10” refractor, but the air was too turbulent to get a good sharp image. We couldn’t make out any bands at all. I think we should’ve tried filters, as the image was quite bright.
Our refractor is a 10” f/13 doublet with a
tri-space corrector, making it a 5-element system. On good nights, it’s incredible.
