The Chandelier and the Cloud
One of most beautiful region in the southern skies, the Corona Australis Molecular Cloud with the NGC 6726 and IC 4812 reflection nebulae and nearby Chandelier Cluster NGC 6723. The later belongs to Sagittarius, though.

Most of the CGs – Cometary Globules – are in the outskirts of the Gum Nebula, CG12 here is located in Centaurus together with the reflection nebula NGC 5367.

A 2 panel mosaic of SHO data in Sagittarius, the reflection nebulae NGC 6589/90 and Surroundings, in particular the emission nebulae IC 1283 und IC 1284. NGC 6590 also seems to be cataloged as NGC 6595.

Oldie, but goldie. The Blue Lagoon, not in Iceland, but in the constellation of Sagittarius, Messier 8 (M8), the Lagoon Nebula. Remote acquistion at the IAS Observatory, Hakos, Namibia.

One of the drop-dead gorgeous objects in the southern skies is the Great Carina Nebula, NGC 3372, of course. Imaged here in narrowband SHO colors with added RGB stars, using the new IAS remote telescope “Dieter”.

Continue readingA Tale of Three Black Holes
With #3 recently discovered in the analysis during preparation of Gaia DR4 data, there are now 3 black holes in the Gaia catalog. Or more precise, 3 binary systems consisting of a companion star and a likely stellar-mass black hole.
So I took the opportunity to capture the corresponding starfields with the new IAS remote telescope “Dieter” at Hakos, Namibia. The images only show the companion stars, of course. ;-)
Regarding the BH3 image, at first I wasn’t sure whether I found the right object, as the catalog gives the coordinates RA=19h39m18.7115472s, DEC=+14d55m54.010992s and the read-out in Pixinsight showed ICRS RA=19h39m18.68s, DEC=+14d55m50.3s. But thanks to the discussion with Ulrich Bastian I found out that it is necessary to take into account the large proper motion of the object, which results in almost 4″ deviation in declination. Calculating the current position for 2024.5 with Astropy yields RA=19h39m18.66368537s DEC=+14d55m50.2085012s.

Almost exactly 10 years ago, I photographed the magnificient Pavo Galaxy with the IAS 20 inch AK3, my first object with such a “big scope”. Here’s the result of June 2024, with much more exposure time on the very same telescope. I originally planned to use my QHY268M with the AK3, but this camera is now used at the new IAS remote telescope. So back to the roots with a ASI294MC Pro one-shot-color camera.
