Within the same field recorded by my STL camera lies a second, smaller and more compact planetary nebula, known as Alv1 (PN G079.8–10.2). It was discovered in 2009 by the Portuguese amateur astrophotographer Filipe Alves, during a deep imaging session of MWP1…Read more
A new exoplanet transit (TOI-12046b) has been added to the Exoplanet transits page.
More information about exoplanets and all the transits recorded here.
MWP1, also catalogued as PK 080–10.1 and PN G080.3–10.4, is a remarkably large and ancient planetary nebula located in the constellation Cygnus. It is commonly referred to as the Methuselah Nebula, a fitting name given its exceptional age…Read more
The Soap Bubble Nebula, formally designated PN G075.5+01.7, is a planetary nebula situated in the constellation Cygnus. It lies remarkably close (approximately 0.7° east) to the well-known Crescent Nebula (NGC 6888), which was the subject of my most recent published image…Read more
While recently reviewing my portfolio, I realised that I had never captured the Crescent Nebula in color, only a monochrome image taken back in 2009 (which is still available on my website). That prompted me to return to this fascinating object and finally produce a colour version…Read more
