RGB, LRGB newbie - where to start....

Hello,

I am taking the plunge into using a mono ccd camera having used a DSLR and OSC ccd previously.

I have a manual 1.25" filter wheel and I have RGB, UV/IR cut and neb filters. They are standard quality filters though as I want to start out without to much expense.

So I am looking for the idiots guide here. I think it best to start with a few mono (L) shots to get familiar with the kit.

Then I shoot RGB at 30s or so of a G2V star to get my filter weightings.

I guess I need will flats for each colour as well as L?

I will need darks to match the L and RGB exposures...or do I keep exposures the same and simply stack more for L?

Then I have the basics for first run...what advice tips do you have for a newbie? I will be using AstroArt4 for capture/processing...

Big learning curve for me...

Would also like to try Ha - is there a recommended beginners Ha filter - the scope is the 127 ED and the camera has a Sony CCD: ICX285AL chip which has a QE of some 55% at the Ha wavelength.
