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.

Mondaufgang über der Schäl Sick am Kölner Rheinufer, einen Tag nach Vollmond unterwegs mit dem Team von Quarks – stay tuned. ;-)
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.

More on-site OSC data from the IAS Hakos observatory, the reflection nebula IC 4601 in the constellation Scorpius.

And one more. ;-) Of course, Omega Centauri aka NGC 5139 is a jewel in the southern sky and a go-to-target. So Omega Centauri’s photons were the “first light” for the ASI 2600 MC Duo on the AK3 astrograph, but I messed up focussing and had to redo it later.
All three globular clusters here in the blog were processed in PixInsight and Lightroom with the same color calibration and processing steps. Interestingly enough, their appearance varies quite a bit!
Also compare this with be previous image of Omega Centauri.

Another globular cluster, only about 9 degrees from M4 towards the constellation Ophiuchus, Messier 62 or NGC 6266 against the dense background star field of the Milky Way.

More processed OSC data with the ASI 2600 MC Duo and the IAS 20″ telescope AK3, featuring the globular cluster Messier 4 aka NGC 6121.
Notable change to my previously shown OSC workflow: I used “K2V star” as the white reference for SpectrophotometricColorCalibration. Standard “Average spiral galaxy” yielded stars, which were too “golden” for my taste, thus this bluer/colder rendition.

This blog post is a quick overview of the processing in PixInsight (PI) for my CG 8 and 9 image. Quite some 3rd party add-ons for PI were used. If time permits I’ll add links to the various tools.
