Fresh out of the oven.

 

My attempt at another region of the milky way after some encouraging results from M22 and M25 with only about 4mins of integration time. The Lagoon and Trifid Nebulae frames up very nicely with a 135mm focal length. I aimed for about an hour of integration time hoping to bring out the nebulosity of both nebulae. Hints of both nebulae can be seen on a single 15sec sub. I was lucky to complete imaging before moon rise.

 

The Lagoon Nebula (M8) is an emission nebula in the constellation Sagittarius. Located 5,200 light-years from Earth, M8 is home to its own star cluster: NGC 6530. The massive stars embedded within the nebula give off enormous amounts of ultraviolet radiation, ionizing the gas and causing it to shine.

 

The Trifid Nebula (M20) is also located in Sagittarius. Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance.

A great image. It is interesting to see these nebula in context against the vast background of stars. It is surprising how small these objects are when you see them both presented in a very wide field.

Wow, very nice! And this is from Bortle 8? Unreal! Shooting with such a fast lens really makes a huge difference. Imagine if you got 90 minutes from dark skies!

Superb image ! Great integration ! Here is my wife field shot last night of that same area - 50 mm f1.8 Nikorr lense shot wide open and then processed on my iPhone - I am at my lake place and can’t process them properly on a laptop until Monday- like you said before the moon came up

Thanks! Widefield images really gives you a different perspective on stuff in space.

Yup, from Bortle 8 zone. I was very happy with the outcome too, F2 lens really reduces the time needed under such light polluted skies.

Nice! I think I can see a hint of the lagoon nebula in your shot!

I have yet to do a wide angle milky way shot yet due to my light polluted skies but it's definitely on my to-do list.

Wide field view with my roof in the corner. 20 lights/10 darks. Shot as JPEGs with a Nikon D5100, 18-55 kit lens, and Omegon LX2, and minimally processed with Starry Landscape Stacker and OS X Photos.
