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).
