dslr stacking and DSS

[Fay]

i stacked a few milky way subs with DSS. it was weird as they stacked as a vertical column, nothing near the full frame. has anyone an idea why this may have happened?

[mickw]

Were all the frames taken in "Landscape" format ?

I believe if one of them is "Portrait" DSS throws a wobbler, they must all be the same format

Make sure you don't have Intersection set as the output result and that you don't have a selection box showing on the files list screen image display as that will get DSS to only process the selected area (good for trying out different settings as it's much quicker).

everything seems to be ok with settings etc but i must have something wrong. all lanscape. will have another go

[Carole]

Have you got another stacking software Fay?
I am sure you used to have Astroart, have you tried that, it often works when DSS fails.

must be a setting wrong somewhere.

in DSS it stacked as a vertical column in bright purple and black.

in Astroart it stacked full size in mono.

in PS it was automatically showing as grayscale, but when i changed it to RGB it was still mono.

in Canon software it shows in colour normally

Is it the 600D?

Most likely cause is that your DSS cannot interpret this fairly recent RAW file format.  Download a later version of DSS.  Check the DSS homepage to see if 600D is supported with your version.

also why is Astroart stack mono

600d yes

DSS version 3.3.2

DSS is opening a single frame in the wrong size. so it is not the stacking
