Another CG image, completed just after Christmas Day, showing CG 15 (lower right) in Puppis and CG 16 (upper left) in Carina. Two more for the growing catalog of CGs here.
More details at Astrobin coming soon.

CG season is also rain season in Namibia, so it took a while to gather enough data for image, adding to the growing catalog of CGs here.
More details at Astrobin coming soon.

Difficult processing with these data: separating stars and galaxy with StarXTerminator doesn’t work well here, too many artefacts. So all the stretching was done with the starfull images, with just a bit of star reduction on L, to preserve the many little, mostly blue stars in the arms of NGC 300.

Some old narrowband data of the Helix was sitting for quite a while on my hard disk. Recently I started to adopt the “Foraxx” palette described in The Coldest Nights blog and used this technique with the SHO data, but combined both the SHO Foraxx and Bicolor Foraxx results, with a bit of RGB mixed in, and added RGB stars. Hope that the result isn’t too bad. ;-)
See an older post for a “classic” rendering of NGC 7293.

[Updated image]
Has been quite a while since I last imaged this large, beautiful spiral galaxy in the southern constellation of Sculptor, NGC 253 known as the Silver Dollar Galaxy, Silber Coin Galaxy, or just Sculptor Galaxy.
A lot of H-alpha data has been used, thus the rendition is different from the DSLR attempts back in 2016.

Continuing the with the cometary globules, here comes CG 11, also part of my growing catalog of CGs here at Gallery > Photography > Astrophotography > Cometary Globules.
More details at Astrobin. Also posted to Spektrum Leserbilder Astronomie.

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).

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.
