    Default Pelican Nebula (IC 5070) Wide Field and Narrow Field



    This is the second test of the Hyperstar, though it is still not aligned correctly. I did shoot twilight sky flats, so the processing was quite a bit easier as the Hyperstar tends to vignette quite a bit. The second shot is a close-up of the central region.

    Wide Field: C9.25 Edge HD with Hyperstar, f/2.3, 30 2-minute exposures, guided with a Lodestar X2 through a Baader Vario-finder on the Astro-physics bracket, processed in Pixinsight.
    Narrow Field: C9.25 Edge HD at f/10, 9 20-minute exposures, guided off-axis with a Lodestar X2, processed in PixInsight.

    Thanks for looking!

    Wow, Gabriel, you're really churning out those 20 min subs. This one is your best in the group, I think.

    The Hyperstar lens replaces the secondary mirror and the camera mounts at the focal point of the primary for a focal length of 540mm which calculates out to f/2.3 for a 235mm aperture.
