Messier 8 - Lagoon Nebula Region - Emission Nebula in Sagittarius
Emission Nebula in Sagittarius
  • Description: There are actually a few nebula in this image but the dominant one is the Lagoon nebula, also known as Messier 8. A number of fainter emission/reflection nebula to the left of that and above is the Trifid nebula, shining in both red and blue. Above and to the left of that a bit is open cluster Messier 21. To the lower left of M8 is a compact globular cluster known as ngc6544.

    This shot is "first light" for a compact imaging telescope called a Redcat 51 from William Optics. It is optimised for astrophotography and they seem to deliver on their promise. Very happy with the detail and resolution from this mighty but tiny telescope! This shot was taken as M8 was descending into residual forest fire haze.
