Barnard 33 and the flame nebula remains one of my favorite targets. The simplicity and complexity of the shot amazes me every time I point my scope towards it. Wide field or close up I am always astonished by its depth.

Thanks, that's a lovely image! The picture is just extremely beautiful.
I also much appreciate your images of galaxy NGC 253 and the Gabriela Mistral Nebula. The reason why I like the NGC 253 image is that it demonstrates something I have never seen before, namely the large gas and dust-free purely stellar halo or outer disk surrounding the well-known inner dusty galactic disk. As for the Gabriela Mistral nebula, I'm usually not a great fan of Hubble palette images, but the large round blue shape of NGC 3324 sitting inside a "wreath of cosmic autumn leaves-colored nebulosity" is very beautiful and fascinating.
In the southern hemisphere, Orion is a summer constellation so seeing it setting in the west in the evenings signals the end of the summer and the transition to longer and colder nights ahead. Venus shining brightly in the twilight is always welcome!
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.

NGC 4535 Black hole with surrounding arms
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.

Geoff, I hope you don't mind, but I inserted a small version of a small part of your image, because I thought it would be nice if people could see something of your image.
Note to everybody: Geoff''s image is much wider, much more highly resolved and, of course, just generally much better. Do take a look at the large version of it!
Welcome, Geoff! Hope we will see more images of yours!

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.
Venus meet Pleiades (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.
