My method for LRGB stacking with DSS is (use the standard stacking mode not mosaic or intersection):
- L: add all the necessary files, make sure to check all the files.
- register the images so that they get scored/rated
- mark one frame as the reference, right click on the file name and choose “use as reference”, a () will be places next to the file to indicate it is the reference. DSS automatically defaults the reference to the highest scoring frame but does not add the (). I personally like to specifically choose the highest scoring frame because the (*) acts a good visual indicator of the reference frame. regardless of if you choose, or you use the DSS default, make sure to note the file/frame used.
- save the file list L_filename.
- clear the file list
- R: with a blank filelist, add all the necessary files, make sure to check all the files.
- add the reference file to the file list. do NOT check the file. right click on the file name and choose “use as reference”, since it is unchecked it will not be included in the stack, but it will align all the sub-frames to this file.
- register the images so that they get scored/rated.
9: save the file list R_filename. - repeat steps 5 thru 9 for the G and B filters.
- you will now have 4 separate file lists saved, one for each filter.
- in registering and stacking, click on Batch Stacking.
- this will open a batch stacking window
- add each of your saved file lists to the batch stack.
- start the batch stacking
- when the batch has completed stacking you will have a final/master calibrated, stacked and aligned image for each of your filters used
- take the master files and add them to the appropriate color channels in your favorite processing program and process your image as needed.
