Lol, well I guess so. What I tend to do is... if I see a feature, I mark it down. Many features are very fleeting due to atmospheric conditions... I make heaps and heaps of diagrams. If the feature crops up regularly, It goes on the planetary map, otherwise it gets discarded. That's why my pics have extra features which may or may not exist.
Oh well u know, some of the best planetary seeing is when there is high clouds anyway, cos of the frozen atmosphere. I always love if there is some cirrus cos that's a perfect polarizing filter, or whatever it is, lol.
However, I am confident that in the hemisphere pointing towards us, there are two visually apparent round white patches visible to the human eyeball, or at least my eyeball, and these are not being displayed on digital cameras/stacked images. Or maybe they are, lol.
