Too bad, because once you do learn it's really fun. Even Hubble's pictures of Jupiter or Cassini's pictures of Saturn are a lot harder to put together due to all the moving they like to do, though. You'll end up with a little moon in three different places so there's a red dot, a green dot, and a blue dot for each exposure where they don't line up.
It is certainly true that I am yet to learn how to process images from separate LRGB channels. And thus far, I have only ever attempted colour astrophotography with a colour sensor. I do have a nice set of colour filters, still in very good condition, in the bottom of an old camera bag at the back of the cupboard. At this early stage in my journey into astrophotography, I figure I need all the light I can get.
But in this instance, I was referring more to the fast rotation rate of the gas giants (and the short orbital period of their moons). In order to get a sharp image of the clouds of Jupiter, one needs to stack an array of images all recorded within a very short time period (30-60 seconds, say). Having to break that into separate channels sounds "too hard" with only one scope and one camera. I know there are semi/fully automatic filter wheels available, but I also still want to purchase a piggy-back mount, a better video camera, a 3x-5x barlow lens, an equatorial wedge, a bigger scope, an observatory, a higher mountain, a spaceport, recycled ICBMs, etc, etc.
Even though I'm only just starting out on the image processing side of things, I'm already feeling that I don't enjoy it quite as much as actually being out under the sky at night. This may prove to be the real
limiting factor of my attempts at astrophotography. It has to be fun, above all else.
