    Default how to removing streaking



    Morning all,

    I was hoping someone would point me in the right direction on removing the obvious streaking from my photos. Attached is one of the Eagle Nebula I took in 2014, and have been working on recently. The red streaking is obvious. Is it gradient? bad guiding? need filtering? wrong darks, flats, offsets, etc?? I have several shots with similar effects.

    The was shot with 10" reflector, Canon 7d. I think this is about 2-1/2 hours of lights.

    Thanks in advance, Bill

    Hi Bill, you didn't say what you were using for processing but looking I'd say you've got some coma down the right hand side which if your using a reducer/flattener then it might be an idea to check the alignment/spacing, and a really strong green tint that's fairly common when processing astro images and can be fixed in one step. As for the banding Canon images are prone the that and in some packages there's "canon banding removal" scripts that can be run following integration that can help remove/reduce them.
    Thanks George

    Thanks so much!! I do have a coma corrector, but not sure if it was in line at that time. I used DSS for the processing. I will have a look for the banding removal tool !!

    Thanks, Bill

    Are you dithering? Is it set for RA only? I did not take time to asses the orientation of the object but that might be one culprit.

    Look into "Walking Noise / Astrophotography"

    Thanks for the suggestion! It seems to be cleaning up pretty nicely with this tool. I can't imagine how it would look if I had any clue on what I was doing with it !!
