    The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

  4. Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) .........

  5. Bright Nebula IC 4628 in the constellation Scorpius. ( a re-processed version can be found in a comment below - colour balance tweaked to add a little blue ) ( another re-processed version can be seen below - this time to increase the vibrance & saturation somewhat ( too much ? ) ( click on image to see full size ) IC 4628, called the Prawn Nebula by some, is an emission nebula in the far southern sky in the constellation Scorpius. Relatively faint, with a visual magnitude of +10, IC 4628 resides in a rich area of the Milkyway about 6000 light years from Earth.

  7. Re-processed to try to bring increase the brightness of the various nebulae and increase the contrast a little without futher blowing out the stars and adding too much noise ... orignial: Orion's Belt - centred on "Alnitak", is a 1.7 magnitude triple star 740 light years from Earth and appears at one end of the belt. The Flame nebula ( cat: NGC 2024 or Sharpless 2-277 ) ( lower centre left of the image) glows yellow-pink due to the ionising radiation that comes from Alnitak. Seen from Earth, the Flame nebula is behind Alnitak and around 80 light years further away from Earth. The Horsehead nebula ( cat: Barnard 33 ) ( centre right of the image ) is a dark dust and gas cloud that is only visible from Earth due to the backlight illumination and silhouetting caused by the bright pink glow from the ionised hydrogen gas in the emission nebula IC 434. The bright blue reflection nebula below and to the left of the Horsehead is NGC 2023. Details: Combination of two sessions over a year apart. Skywatcher Quattro 10" f4 Newtonian.

  9. Tarantula Nebula ( NGC 2070 ) in Large Magellanic Cloud ( LMC ) by Mike O'Day. The Tarantula Nebula ( NGC 2070 ) is the largest and brightest emission nebula in the nearby irregular galaxy, the Large Magellanic Cloud ( LMC ). At a distance of 160,000 light years away from us, the Tarantula Nebula is so bright that it would cast shadows on the Earth if were as close to us as the Orion Nebula in our galaxy. New version ( April 9 ): ( please click / tap on image to see larger and sharper image ) ............ Older versions: And here it is re-processed to try to reduce the red background ( due to light pollution I think ) without impacting the colour of the stars too much ( please click / tap on image to see larger and sharper ) Details: Nebulae: NGC 2070 Tarantula Nebula NGC 2048 NGC 2060 NGC 2077 Open clusters: NGC 2042 NGC 2044 NGC 2050 NGC 2055 NGC 2091 NGC 2093 NGC 2100 Image centre ...
