    Description

    The ASI1600 with its 3.8µ pixelpitch is a nice match for FSQ106 with reducer at 385mm. The wide field shows the corridor of dust, at the end of it lurks the Cocoon in its dust shell. There are weak Hydrogen clouds present in the area, that overlay with the dusty areas and make it difficult to feature all the different details in the mixing colors.
    LRGBHa on two clear nights, ASI1600 at lowest gain.
