Another CG in Puppis, also called “God’s Hand” trying to snatch PGC21338, but for me it looks more like a sandworm.

Cometary Globules CG30, CG31, CG38
New data from the IAS remote telescope, comprising 2 panels for this mosaic. Somewhat uncharted territory in Puppis, at least regarding the NGC and IC catalogs, with several cometary globules in the outskirts of the very large Gum Nebula.
More scientific details about the objects can be found in this older publication by ESO, see page 71, section 2.1.4 CG30/31 and HH12.

Final installment of the OSC data from April/May, taken at the IAS Observatory Hakos, Namibia. Somewhat well-known objects in the southern sky, NGC 6188 and 6193, imaged as a two panel mosaic.

And yet another image from April/May at the IAS Observatory Hakos, Namibia. NGC 3621 is a field galaxy, i.e. lonely galaxy ;-), in the constellation of Hydra.

Another image from April at the IAS Observatory Hakos, Namibia. Designated RCW 32 or Gum 15, an emission nebula in the constellation Vela.
Meanwhile I started using PixInsight’s new Weighted Batch PreProcessor (WBPP), with the option to split the R, G, B channels in the Debayer process and align / integrate the channels separately. This really improves image quality with OSC and using WBPP takes over the otherwise tedious manual process.

Already done in 2019, here comes another shot at NGC 2997, a face-on unbarred spiral galaxy in Antlia. Only 1 hour of total exposure time due to many technical problems with the 20″ Cassegrain.

Finally, something fresh from Namibia, captured on-site. Details at Astrobin.

A northern sky object (by just a few arc minutes ;-) from southern skies.

More H-alpha
A completely clear night – not that many of them lately – provided several hours of H-alpha to catch the nebulosities above. Meanwhile I switched from the Optolong LRGBSHO filter set to the new Baader CMOS-optimized filters. At least H-alpha seems to work better in the combination with the Esprit 100 ED and QHY 268M, but still some problems with the flats.
See Astrobin here and here for details.

Because it’s that time of year … a fresh shot at a very familiar target during two clear nights in October. Ha, L, R, G, B with the QHY268M, but still facing problems with the Esprit and the Optolong filters.
