Quote:Discussion on color perception
Quote:Jason, It seems Jupiter is better this year. It could be several reasons. First, there is more to see this year. The festooning is more prominent and the rift in the NEB was not really apparent last year. Last year, the NEB sported a bunch of barges, but not much else. And the GRS wake was evident. This year, whoa, the EQ zone belt and more is visible. Second, it's gotta be some experience and training. This is my second season observing Jupiter, followed by Mars and Saturn earlier this year. This season and last, I observed planets very frequently and almost exclusively. The scope is perfectly collimated and cooled, and it's operating in nearly perfect seeing for a 6" aperture. So, those factors, plus a little effort and perseverance are really paying off. I also suspect one modification to my scope is playing a role, too. But, it's hard to quantify. In fact, at first I was unsure if there was any improvement at all. But, there indeed might be. Even when seeing drops to about 7/10 or below during some rough moments, they are difficult to see. But, when the atmosphere just seems to freeze into place more often and for longer periods, they show up. But, it still takes a good while (about an hour) to really note all of those features. For example, it took several crisp views to kind of see the NEB rift was indeed segmented and not one single feature. But, all those features are, indeed, visible in a 6" aperture when it all falls together.
