Yesterday I've got my new tracker (iOptron SkyTracker), and took about 30 shots of the Orion Nebula (with my Canon EOS 6D and 70-200mm f/2.8 lens at 200mm, f/4, 6s exposure of each frame) and got home.

Here is a (cropped) sample from one of the raw files, and they are all the same, almost perfectly aligned etc:

All the other raws are perfectly normal like the image above. I've fired up DeepSkyStacker, filled the raws, (as this was just a tracker test, I don't have dark or flat frames) and gave it a spin with the recommended settings. After about 10 minutes, this is the result:

The result is just a glitch image consisting of vertical bars. Here is my recommended settings:

I also don't think there is any problem with reading the raws or aligning them correctly:

I haven't touched my stacking settings, it's as they are by default. What have I done wrong?

  • It appears that you may have an image of the image histogram information. (A wild guess) Is there a chance that you are imaging the wrong data file that might be corrected in preferences? – Stan Apr 7 '18 at 19:05

Before using Deep Sky Stacker, Use a RAW image preview application like "Adobe Bridge"(or Other App) to review and organize your images. Any photos with football-shaped stars from hiccups in auto guiding are tossed in the recycling bin. The same goes for frames with airplanes, satellites or passing clouds.
