DSS. How to stack monochrome images with different bin modes?

Dear fellow astrophotographers,

I just started using a monochrome camera and I got an issue with DSS.

I took my luminance images using bin1, then took RGB using bin2.

I selected a luminance image to be used as a reference image for DSS to align every channel which has worked well.

The problem is when I open the tif files in photoshop, the RGB images are much smaller (1/4) than the luminance layer. I can resize them in PS but then need to realign everything where the whole point was to get them aligned in DSS first place.

Is there any trick I missed on DSS to resize the bin 2 images so everything is ready to assemble the color image in PS? I suppose I could drizzle but it's a bit defeating the reason for bin 2…..🙄 Help would be greatly appreciated!

Thanks!

I also bin L 1x1 and RGB 2x2.  In DSS you have to stack each channel separately with the appropriate calibration files.  Once completed I open each file in photoshop and change the size of the 2x2 RGB to match the 1x1 L.  Save those files and then register and stack them in DSS using the L as the master reference frame.  Ensure you check the box for create a registered/calibrated file for each light frame.  After DSS is finished you will have 4 calibrated and registered files that you can post process in the program of your choice. The files will be located in the same folder(s) that you loaded the lights from.  Discard the autosave tiff or fit file that DSS generates as it is of no use.

Hope that helps.

Yes it clearly helps thank you. I didn't realise you had to use twice DSS with PS in the middle to resize the frames. I will certainly try tomorrow!
