The Lagoon Nebula M8 in Sagittarius
Stellarvue SV80 f/6 Astrograph
Uploaded 8/15/23

 
This
            week I would like to share with you another new shot from our
            exceptionally dark site up in Happy Jack Arizona. This field
            around M8 the Lagoon Nebula is about 4 degrees wide, and also
            contains on the left side the beautiful dim emmission nebula
            NGC6559. Notice the dark dust lane running almost all the way
            around the pair, and indeed - the bright emissin nebula are merely
            the illuminated portions of a much larger dark molecular cloud.
            The transparency this night was exceptional, with an SQM reading
            of 22.0 for most of the night. Technical details: Stellarvue
            80mm f/6 refractor, ASI071mcpro CMOS camera, 1 hour exposure.
