Lucky last! From very close to the same time as the first one posted. I forgot to rotate the first two, but remembered to do it on this one.
Wow John, to my eye this is your single best effort at imaging Jupiter to date; it looks like you're making excellent use of your new Astronomik RGB filters with the DMK. I especially like the detail in the white area surrounding the GRS and in the swirl formations within the NEB.

Thanks mate but no, this was done using the one colour shot DBK
How many frames do you take and how many do you stack?
I have exactly the same scope and camera as you and my attempts don't even come close to this level of image (but I'm working on it!)

Hi John.
On average I acquire between 4000 - 4300 frames @ 30FPS.
As to how many I stack, that depends on the seeing. I always work with 'lowest quality' of 98% in registax. If the seeing is great it'll want to stack at least 3/4 of the frames but in average seeing it'll only want to stack a few hundred.
To be honest, I have seen no real advantage in RGB imaging over colour one shot in average seeing. I'm only talking mono DMK versus the colour DBK here of course.
I haven't had any outstanding seeing where I am & I don't expect to either. Once you've studied laminar flows; 3 layer air flows, jet interaction & what happens to seeing if you are living on the east coast of a land mass, you begin to realize a few things.
RGB imaging will come into it's own, but not on Jupiter this apparition for me.
- esp for that DBK. Just goes to show the major effect of atmospheric turbulence.
