Centaurus A, Fourcade-Figueroa Shred, NGC 5237
This extraordinary trio of objects are the result of a galaxy shredding encounter... a violent encounter between an elliptical galaxy and a smaller companion spiral galaxy that took place some 500 million years ago.
Hogg Catalogue of Open Clusters (1965)
The twenty two Hogg open clusters offer an unusually rich observing project - not because the clusters themselves are rich - indeed, many of them are notably obscure - but because they all lie in exceptionally lush and beautiful star fields, with many of them juxtaposed with lovely NGC and Trumpler clusters.
Ara, A Southern Delight
Ara may be small and it may not compete well with its magnificent neighbours, Scorpius and Sagittarius, when it comes to objects big and bright and abundant… but it really is an astronomer’s delight, for it offers something special for everyone.
Pişmiş Catalogue of Open Clusters (1959)
The twenty four Pişmiş open clusters make a delightful observing project. A few of them are exquisitely bright and delicate, others appear as tiny glints of stars mingled with a faint hazy glow of unresolved starlight, and yet others appear as little more than a faint and tantalizing mistiness.
Bochum Open Clusters (1975)
All but two of the fifteen Bochum open clusters reside in the southern hemisphere and can be found along our summer Milky Way in Gemini, Monoceros, and Puppis, with a couple in our rich winter Milky Way constellations Scorpius and Sagittarius.
The Fabled Zodiacal Light
In the pre-dawn sky this morning the zodiacal light was a huge, tapering pyramid of shimmering silvery light stretching up almost 50° into the heavens; its core glowing brightly enough to extinguish many of the fainter stars within it.
