I haven't really done much AP, but I asked a lot of questions on an astronomy forum, heading in the direction of AP.
Yes, I think it's quite hard. Expect a steep learning curve.
You're supposed to get the exposure right, or as right as possible, then put the image in DSS. I think processing in DSS would lower the noise and make it possible to brighten the image, though.
You kind of have to get what you can & process it later with dim objects, alough this isn't so true with the Milky Way, it's bright. A lot of processing in AP.
A telescope is a camera lens & vice versa.
If you can't get a bright enough image, you need a drive, I didn't have one, a major reason I haven't done much AP.
You can run the ISO up, and use a 24/1.4 on ff at 3200.
I got a nice Milky Way shot by running up the contrast into the stratosphere and converting to B&W.
Hers a good overview imo:

AP just doesn't seem to have the same sharness requirements as regular photography. Everything is moving, it's hard to get the drive aligned, etc.
You can learn a lot from an astronomy forum, plus you can ask a lot of questions on the problems that are virtually guaranteed to pop up
