    Default DSLR image, Rho Ophuichus at 55mm.



    Hi,

    Here's another wide field, Rho Oph.

    This is one of those area's that I find difficult to process, this is my best attemt so far, out of six.
    When imaging I tried a ten minute exposure at ISO 800 and a five minute at 1600, in both there was too much fogging of the background. So I stuck to my tried and true five minute ISO 800.
    There's still a bit of noise in this image so it needs some more data.

    Telescope 8” f/4 astrograph on a HEQ Pro 5 mount, orion mini guider.
    Unmodded Canon 1100D piggy backed 55mm at f/5.6
    7 x300 sec subs ISO 800,
    24 dark frames, 9 flat frames and 11 bias.
    Stacked in DSS and post process in Phototshop.
    Cheers,

    Justin.

    Hi Justin, that's a very good shoot... like the nice and soft colors. Hope the weather let me try this area...

    Thanks for share it!

    That's a nice image. I'm surprised no one else has said so. I think the normal AP crowd is out imaging rather than surfing the forum with summer weather. Tough crowd right now.
