The supernova remnant SNR G206.9+2.3, a rarely imaged object, is located in the constellation Monoceros, close to the border with Gemini. Its designation follows the standard galactic coordinate system used for cataloguing supernova remnants within the Milky Way. SNR G206.9+2.3 was first identified and characterised in the early 1970s, primarily through radio observations conducted by R. D. Davies...Read more
The image presents two fascinating main objects, NGC 225 and van den Bergh 4 (vdB 4), both located in the northern constellation Cassiopeia.
NGC 225, also known under the catalogue designation Collinder 7 and sometimes referred to as the Sailboat Cluster, Read more
LBN 777, also known as the Baby Eagle Nebula or Vulture Head Nebula, is a delicate reflection nebula located within the Taurus Molecular Cloud complex, recognised as one of the closest stellar nurseries to our Solar System. Its distinctive shape, sculpted from interstellar dust and faintly illuminated by surrounding field stars, resembles the head of a bird…Read more
The Helix Nebula, designated NGC 7293 and also catalogued as Caldwell 63 (*), is a remarkable planetary nebula in the constellation Aquarius. It was discovered by Karl Ludwig Harding, probably before 1824…Read more
Comet C/2025 A6 (Lemmon) was discovered on 3 January 2025 by D. Carson Fuls during the Mount Lemmon Survey in Arizona. At the time, it appeared extremely faint (magnitude ~21.5) and was initially mistaken for an asteroid, until subsequent observations revealed a condensed coma and a short tail…Read more

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
