LRGB Tutorial

 

using maxim dl4 and photoshop cs

Open and process all 4 groups of subs in Maxim do any stretching or tweaks that you would normally do in Maxim.

Save them as mono Fits files


Open all four processed images in Maxim















Once all four are open choose PROCESS > ALIGN















You are then presented with the choose file pop-up. Add all four files
































Using auto-star matching > overlay all images this will generate a combined image (this just helps to check things are ok) then click OK.

You should now be back to 4 images, then SAVE ALL
















Now you can close Maxim and open Photoshop.

Open ONLY the R G B images into Photoshop using FITS Liberator














You can tweak each image until you are satisfied but do not change the image type.

Once you are happy with your images go to the CHANNELS panel, click on the little arrow top right and you are presented with the following menu.













If MERGE CHANNELS is grayed out then go to each image and LAYERS > FLATTEN IMAGE.

Once all three images are flattened the MERGE CHANNELS should be selectable.















Choose 3 channels, and then select in order your images R then G then B

Each channel is then ALPHA and if you turn them all on this is what you get.


















DONT PANIC, this is normal.


Now convert the image to RGB



















PHEW, that is better!


Now, once tweaked to your taste open the Luminance image, then SELECT > ALL

Then COPY


Select your RGB image and PASTE


















Where has all my colour gone??  again.... DONT PANIC!


Now in the Layer properties choose LUMINOSITY
















And your colour SHOULD come back



















You can turn the LUMI. layer on and off to see the difference before and after.


Any further processing is now down to you.


GOOD LUCK!!
