M8 Lagoon nebula M20 Trifid nebula

Constellation Sagittarius is full of deep space objects. I think we all agree that the most beautiful one is the Lagoon nebula, accompanied by the Trifid nebula. I captured these nebulae already, but with a much longer focal length. This time I used a significantly shorter telescope – only 180 mm to reveal the other deep space objects. The bright star at the bottom left is the star Kaus Bolearis, where the archer has his head. This star is surrounded by the globular clusters: M22 Great Sagittarius cluster on the left and M28 on the top.

M8 Lagoon Nebula, M20 Trifid Nebula

These two magnificent nebulae are located visually close to each other in the constellation Sagittarius. This means we are looking in direction of the galactic core of the Milky Way. Trifid Nebula (up left) is a combination of a reflection nebula (blue part), a dark nebula (brown clouds), an emission nebula (red part), and a star cluster. On the other hand, the Lagoon nebula (right side) is an emission nebula – a giant cloud of ionized HII gas. Due to very low southern declination, it’s very difficult to photograph these deep space objects from my home place in Central Europe. Therefore every time I travel south, I take the opportunity and recapture these nebulae. My first attempt of M20 was done with focal length 917 mm, the second one with 630 mm and now I used a gentle focal reducer. Focal length 570 mm allowed me to fit both nebulae into the field of view of APS-C sensor size. The picture is an integration of 213 minutes, taken under the dark skies of Fuerteventura.

M8 Lagoon Nebula

Lagoon nebula (sometimes called Messier 8) is a giant intergalactic cloud of ionized Hydrogen. The nebula is located in constellation Sagittarius and it’s 4100 light-years away from Solar System. It belongs to one of the brightest nebulas visible from northern hemisphere.

I have to admit, this nebula was the main reason and target of the trip to Milos and it was the first deep space object captured there. When I processed the picture I was so happy that the nebulosity is so clearly visible without any narrow band filters. Well, mission accomplished.
