Ray,

The process is pretty straightforward in Photoshop.  I normally start by opening the Red, Green, and Blue Images.

I select the Red Image - make sure the to check Image > Mode > RGB is selected - not grayscale.  Next Open the Layers window and select Channels. You will now see each of the channels - R, G and B.

Then respectively select the Green then Blue Images and paste them into their respective channels.  After assembling the RGB, I save under a new name, e.g. Stars RGB.psd.

Then switch back to the Layers mode, and open, select and then paste the Luminance image in (on top of) the new RGB image.  And finally, select the Luminance Layers Blending mode from the Layers Window.

That's all there is to it...

Hi Guys,

I've just got all the gear I need up-together (Camera, Filterwheel,
filters and of course Astro IIDC) and I've taken for movies in R,G,B
and straight b/w for luminance. This is in the daytime and its the
emblem of my Rover car that is sitting on my driveway. Now I wish to
assemble these as a composite LRGB colour image using Photoshop (yes
I managed to get a working version of CS1 on my new iMac). I've been
searching the web for hours but had no joy so any tips would be
gratefully received.

TIA
