Beautiful, Bogdan Borz. I have just become aware of your great astrophotography.

What I love most about your picture is that it "puts Westerlund 2 into perspective". When I looked at your picture of the Carina Nebula, I recognized everything in it except the little blue crescent at upper right. The reason why didn't recognize it is because I had never before seen a wide angle picture where we can actually see the location in the sky of this great cluster and nebula.

April 23, 2015: NASA and ESA are celebrating the Hubble Space Telescope's silver anniversary of 25 years in space by unveiling some of nature's own fireworks — a giant cluster of about 3,000 stars called Westerlund 2. The cluster resides inside a vibrant stellar breeding ground known as Gum 29, located 20,000 light-years away in the constellation Carina. The comparatively young, 2-million-year-old star cluster contains some of our galaxy's hottest, brightest, and most massive stars. The largest stars are unleashing a torrent of ultraviolet light and hurricane-force winds that etch away the enveloping hydrogen gas cloud. This creates a fantasy celestial landscape of pillars, ridges, and valleys.

ABOUT THIS IMAGE: The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in the 25th anniversary NASA Hubble Space Telescope image to commemorate a quarter century of exploring the solar system and beyond since its launch on April 24, 1990.

NGC 4535 is a barred galaxy and one of the largest galaxies in the Virgo Cluster, a massive cluster of as many as 2000 galaxies, about 50 million light-years away. Although the Virgo Cluster is not much larger in diameter than the Local Group — the galaxy cluster to which the Milky Way belongs — it contains almost fifty times as many galaxies.

The small nucleus is of type HII, meaning the spectrum resembles that of and H II region, as you can see if you make zoom, you will see it.

Thank you for doing this, Miguel Ángel García and Lluís Romero. I googled NGC 4535, and there existed no really good highly resolved picture of this galaxy until you posted this processed version out of Hubble data.

Thanks again!

Associated with this galaxy is HIPASS J0731-69, a cloud of gas devoid of any stars.[3] It is likely that the cloud was torn loose from NGC 2442 by a companion.

(clean photo without labels available)

At this time you can observe an interesting encounter between Venus and Pleiades in the constellation Taurus. Visibility may be worse because of the present moon, but it also opens up new possibilities for creative photography.

The object in the background is the Remote Radar Post in Stara Ves nad Ondrejnici, Czech Republic. This RRP is (as far as I know) in operation since 1977 and the last known unit present at this station was in 2003. Current inhabitants of the base are unknown, but the place is still guarded by a military unit.

https://www.astrobin.com/full/8aalro/C/

IC 2631 is a blue reflection nebula in the far southern constellation of Chamaeleon. It surrounds a young T Tauri star HD973000, about 500 light years away. It lies in the Chamaeleon Cloud Complex which is a large star forming region that includes the Chamaeleon I, Chamaeleon II, and Chamaeleon III dark clouds. The Chamaeleon Complex occupies nearly all of the constellation Chamaeleon and overlaps into Apus, Musca, Carina and Octans. The dust partially or nearly totally obscures the stars within and behind it.
