IC 1274/1275/4684/4685, NGC 6559 – Nebulae in Sagittarius – SHO w/RGB Stars v1

An assortment of nebulae in Sagittarius, very close to the well-photographed Lagoon, thus sort of completing the Lagoon footprint, which made me come up with this nickname.

This is a narrowband (SII, H-alpha, OIII) plus RGB image. For rendering the NB data, I used the “Foraxx” palette described in The Coldest Nights blog along with other techniques. Worked rather well, a pure SHO approach would yield a very green image. Stars are color-calibrated RGB.

Emission and reflection nebulae in this field: IC 1274/1275/4684/4685, NGC 6559

The strange object below and right of NGC 6559 is the planetary nebula PN M 1-41
(RA 18 09 30.10, DEC -24 12 26.0).

Nach 2017 brachte uns wieder eine Sonnenfinsternis über den großen Teich in die USA, im April 2024. Die Wetteraussichten favorisierten Texas, daher ging’s dann dort auch hin. Das mit der Sonnenfinsternis wurde noch spannend, aber zunächst einmal standen die Städte Austin, Houston und Galveston auf dem Programm, deren Portrait sich in dieser ersten Bilderserie findet.

After 2017, another total solar eclipse brought us back to the US, in April 2024. The weather forecasts favoured Texas, thus that’s where we went. Things turned out a bit differently with the eclipse, but the first part was a visit to the cities of Austin, Houston, and Galveston, portrayed in this first series of images.
