The 'A' List - The Ultimate Astrophotography Challenge

The Ultimate Astrophotography Challenge!

Astronomers, both professional and amateur alike, thrive on lists and catalogues. There is the Messier list of popular Deep Sky Objects (DSO), the Caldwell list of 109 other DSO’s, the Herschel 400 List, O’Meara’s Hidden Treasures list; the Dreyer New General Catalogue (NGC), the Index Catalogue (IC), the Principal galaxies Catalogue (PGC) and so on. List and Catalogues for DSO’s, Galaxies, Planetary Nebula, Dark Nebula, and Bright Nebula and…

However, there is no list specifically for the Astronomical Photographer, which catalogues the best subjects for imaging – the most beautiful, the most colourful, and the most interesting.

ArtdeCiel.com has created such a list – the 'A' List, comprising just like Messier’s of 109 objects, but including not just DSOs, but Planets, Lunar Features, and Earth related phenomenon like the Aurora and a simple Sunset.

Each object in the list is given its own number prefixed not by an ‘M’ as in Messier’s List, but by an ‘A’, so A1 in the list is the Aurora; A2 is the ‘Horse Head’ Nebula (Barnard 33); A24 is a Comet; A29 the Planet Jupiter; A50 the Lunar Feature known as the Mare Imbrium – the ‘Sea of Showers’; and A67 is simply a ‘Sunset’ and so on. 

The ‘A’ list is not only very diverse, but also challenging for both experts and beginners.

So, be the first to acquire all 109 objects!

You can download (see below) a detailed schedule of each object in the 'A' list as well as an article describing the thinking behind it.

About the Author

Stefan Hughes has been observing the night sky since he was 12 years old, when he got his first telescope a small 3.5" Reflector, which was in his own words 'pretty useless'. He then got his first serious telescope three years later - a 6" (15cm) equatorially mounted Newtonian Reflector, which he used to look mainly at the moon and planets. He was so taken with Astronomy that he decided to make it his career, though ironically becoming a theoretical astronomer specializing in the field of Celestial Mechanics, being a student of Desmond King-Hele and the late Andre Deprit. In 1978 he was awarded a PhD for his thesis on the motion of Artificial Earth Satellites, which was published as a series of papers in the Proceedings of the Royal Society. After spells as a Research Fellow and University Lecturer he moved into the world of Computers when work became scarce in Astronomy, as a software designer and later project manager. During this time he drifted out of Astronomy, concentrating on his career and raising a family. He also had a further career change and spent five year training to become a Genealogist and Architectural Historian; which he practiced professionally for a number of years. In 2001 he moved to the island of Cyprus with his wife, and is now semi-retired devoting the majority of his time to his rekindled enthusiasm for Astronomy and in particular to Deep Sky Astrophotography, and of course the 'Art de Ciel' website. He is currently writing two books one on the history of astrophotography called ‘Catchers of the Light’ and the second a biography with the photographic historian Dr. Marcel Safier on the Victorian Photographer Frederick Scott Archer entitled ‘To the Sons of the Sun’.
