    Default How much will domestic light sources interfere with photos?



    As the title says. I live in an area where there are street lights within 200 feet. If you're looking within 30 degrees of "straight up" viewing is alright but viewing any further down the light pollution really starts to become a problem.
    I imagine this would be a big problem when taking long exposure photos. Has anyone tried under these circumstances? What kind of results should I expect trying to shoot under these conditions?

    Hi!
    I image from a suburban backyard in southern Australia. When I first started, I experimented with exposure times to see what I could get. I was down to less than 2 minute exposures, which is nothing really.
    I then purchased an Astronomik EOS clip filter for my Canon 40d, and could get up to 20 minutes with out having huge processing problems with gradients and colour shift from the filter.
    Colour shift is minimal, gradients can be a pain, but that is in the art of processing, as Astro Imaging to me is 2 parts, capture good data, process the data well.
    I then moved to a Cooled CCD, a QHY8, and bought an IDAS LP2 light pollution filter for it at the same time, excellent results straight up, but I won't image too low down still.
    I am now in the process of moving to a QHY9 Monochrome and I will still intend to use my LP filter for LRGB work.
    Narrow band imaging does not suffer so badly from light pollution, except for OIII seeming to suffer a bit, so you could go down that road, but you will need to use a monochrome camera and filter wheel. Depends on your inclination and dedication. Try some imaging, if you like it, then buy a really good camera.
