    Hello everyone,

     

    Since the month of November that I waited for a suitable sky to resume astronomy. It is done with my last image realized on the months of January and February.

     

    SII : 20x900s
    OIII : 20x900s
    Ha : 22x900s
    RGB for color stars : (24x300s)x3

    I hope you'll like her.

    Hello,

     

    Here is the last image made with the Newton ASA10 ". This is a mosaic of 4 panels on NGC6992/NGC6995.

    80 hrs total exposure. I'm happy with the colors but I can not insert the RGB stars in a clean way ...... :(

    I take your tips and hints in Photoshop.

    It's really hard to add the RGB stars on the SHO layer especially with the egrets of diffraction .....

     

    Thank you very much

    Hello,

     

    NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. This sharp telescopic portrait uses narrow band image data that isolates light from hydrogen and oxygen atoms in the wind-blown nebula. The oxygen atoms produce the blue-green hue that seems to enshroud the detailed folds and filaments. Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. The nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

    Thank you very much Mark. 

     

    I also believe by far the picture N ° 2. I always wanted to do the images with the colors according to the Hubble palette but in my case, it makes less good :)
