    A Bubble Nebula color picture.
    The raw data were taken from 2014->2016 by Mr. Morten la Cour and Niels V. Christensen.

    The equipment/gear used by Morten:
    Orion Optics ultra 300 f/4 mirror. TS 2.5 inch Wynne corrector, AP1600GTO, Qsi660wsg, SX superstar OAG guiding, Astrodon 5 nm filters, Ha.

    The best Ha frames (with the lowest FWHM) was used as Luminace info. to make this detailed picture of the Bubble Nebula.
    It is shown as a Lum(80%Ha)-LRHaGOIIIBOIII picture.
    Ha exposure data from Morten la Cour: 71x300sec.

    Here's a dropbox link to Morten's Ha picture,

    The 1. uploaded file was not shown correctly, why? I don't know why also the 2. version of this picture only will be shown/visible when the cursor is placed on this, x/picture place, strange? Now fixed/corrected, thanks!
