So as most of you might know, Jupiter is covered with low-contrast details that are easily washed out in even moderately bad seeing. But in the past previous nights, I've come to the realization that transparency too plays a part in observing these details.
Few nights ago, I had hazy weather with very excellent (sub-arcsecond seeing). The airy disk and the first ring was easily visible in both my 6 inch and 10 inch scopes. If I had to guess, I would say it was around Pickering 8.Transparency was horrible though, with NELM hovering around 3.5(average where I live is 4.5-5). Even looking naked-eye, one could easily see that the planets appeared a lot dimmer.
Jupiter showed a lot of detail that night, and appeared very sharp; in fact at that time I thought I had near-perfect conditions for planetary observing.
Two or three nights later however, I had the luck of witnessing a truly excellent night for astronomy, with both excellent seeing(same as the previous mentioned night) and excellent transparency(NELM approaching 5.5). These sort of conditions are quite rare where I live, as this was the first time I experienced them.
However, on this night I could see more detail on Jupiter than ever before. Especially the small scale details like turbulence in the bands seemed to pop out more than before. Seeing the 'string of pearls' was easy in the 6 incher as compared to before, and could pick out a lot of detail in the polar regions with the 10 inch scope. The colors also appeared more vivid.
Now I don't know whether this was me not judging the seeing well enough, and actually the seeing was better on the latter night; or it was the fact that transparency plays a role in planetary observing, which is why I wanted to hear your thoughts on this
