well done muddy!!!
that single frame, i believe could be brighter, ie more gain or higher exposure. do not be worried about using higher gain. stacking will dramatically reduce the noise.
with raw mode, you want great seeing to make use of it. It is easy to implement ie get your camera into raw mode, but it only operates at 5fps. so you either image for longer to get 500 to 1000 odd frames, or with someting like jupiter which rotates so quickly, you are restricted to 90 seconds capture ie 450 frames. so theose 450 frames had better all be in focus! - hence great seeing.
raw is great for star work and dso's etc. I believe it brings out more detail in planets, but as rob says, you need everything else spot on.
I would say tracking would be essential otherwise you need twice as many passes to get a decent amount of avis!!
Let us know how jupiters goes, It has its opposition in May, so the more practise you do now the better. Also saturn is around at night when everything is still cooling ie 10 - 12pm. Jupiter is around from 4 - 6am. Everything is still and stop cooling, so a telescope will have everything the same temp ie no tube currents. It is worth leaving the scope out if the weather looks great and getting up. The seeing will be better
keep at it!!
