Sharpless 2-1
Emission / Reflection Nebula in Scorpius
Uploaded 6/24/24

 
A spectacular
            blend of red hydrogen and blue and yellow dust can be found in
            the claws of Scorpius called Sharpless 2-1. This new image was
            a two part mosaic with two separate instruments. The Hydrogen
            alpha was imaged for 2 hours with a RASA 8 and IDAS NBZ mark
            II filter, and the RGB and reflection components were with a
            Stellarvue SV80S and a UV/IR blocker filter. All four sets of
            data were combined for this new image. Exposure: 4h total, ASI2600
            MC CMOS, Happy Jack, AZ.
