Antares, Full Color
Lots going on in this 22 minute exposure at f2.8. Antares is the yellow star to the middle right; it lies in the heart of the constellation Scorpius the scorpion.To the left, buried in the nebulosity, is a small globular cluster NGC 6144, and above M4, a larger globular cluster. Toward the left edge of the screen the red emission nebula fades into the blue reflection nebula, and then into a large dark nebula (B44 I think). Nikon F2 camera, Nikon 300mm f2.8 ED lens @ f2.8, 22 minutes exposure, Kodak LE 400 film, and the usual astro processing in Photoshop.
Here's a similar Antares view with a DSLR. 255 seconds at ISO 200, Nikon D100 D-SLR, same lens as above. I used the in-camera noise reduction function.
Combined version of two DSLR Antares images. Note that while missing some of the red emission nebula due to weak red response in the DSLR, the blue reflection nebulae are picked up nicely.
