IC4601 in Scorpius
with 10" f/3.9 Astrograph
Uploaded 7/14/23

 
This
            week we would like to share another new image with you of IC4601
            taken during the May-June timeframe. This started out as a "Junk"
            object - something to shoot while waiting for the really good
            objects to rise out of the horizon haze for an hour at the start
            of dark. But the more we shot this amazing nebula, the better
            it looked. This final image, a total of 4.5 hours of integration
            time reveals a gorgeous blue irregular cloud of nebulosity surrounding
            a set of B type stars reflecting thier high energy light. Look
            closely, and you can see a dark ring around this object, which
            is the unilluminated part of the dust surrounding this double.
            We are now very glad to have chosen this object to waste time
            on! Thank you again for looking, and enjoy our latest contribution.
