    Default First try at a star trails



    Good day,

    Here is my absolute first try at a star trails photo. There is no stacking, no editing. This is a 10min shot. I believe at ISO 200 and F9 with the 50mm 1.8 Yes there is some light pollution where I am. I will try to go to a darker site.

    This was taken in raw and then simply transferred to my iphone with the canon app.

    Please let me know what I could do differently. I was actually pleased with the result though.

    That is just what it should look like from a fairly light polluted location. A darker site will certainly give you better results. Your focus might be a tiny bit soft.

    Achieving perfect focus is everyone's nemesis on all types of AP images. You've done quite well for your first attempt.

    Cheers,
    JT

    Looks like you kept the imaging camera solid. Moving the camera is a possible source of error. Nice job!

    With that camera I am able to control it from my phone. I can control the exposure settings from the warmth of my house. However, once the screen of the phone turns off, then it stop control so it closes the shutter. I now have a remote. The tripod I have is pretty cheep but for now it gets the job done. I did not lock the mirror. I set the focus as far as it would go.

    Nice setup. One thing to note; at least some modern cameras and lenses allow you to focus a little past infinity, so winding the lens out all the way isn't quite as trustworthy as it was in past times. That may be happening here and contributing to the soft focus JT referenced.

    Actually it is funny you mention that. I was surprised at how much Polaris actually stands out.
