NGC6559 and surrounding nebulosities in Sagittarius
with 10" f/3.9 Astrograph
Uploaded 10/5/23

This week Id like to share with you another newly completed image, NGC6559 and the surrounding hordes of blue and red nebulosities. This extremely complex and beautiful region includes not only NGC and IC nebulas, but Barnard dark nebula, Sharpless catalog objects, and a whole slew of amazing colored double stars. I wont detail each object here, that you can do with your favorite charting program, but I will point out some interesting features. This image is G2V color balanced and shows reasonably true colors for both the nebula and stars. Notice how the nebula is pink in the center, gradiates to deep red on the periphery, and on the lower right edge again a strong pink coloration due to Hbeta contribution. Several exquisitte blue reflection objects are seen here. Below center is part of NGC6559, but the glowing bulbous pillar above is rimmed in a blue reflection. Thats Sharpless 2-32. At top that little intense blue puff is IC4684, and the cluster of stars on the top right edge is NGC8546. Finally take note of the beautiful blue and gold double star on the right edge, surrounded by a wisp of blue relection. Technical data: 10" f/3.9, Baader MPCC, Atik 16200 CCD, 3h total integration time. Payson Arizona.
