This is a wide field image I captured of the Trifid Nebula and Lagoon Nebula in the constellation Sagittarius. No filters were used in these images and it was imaged with the ZWO ASI2600mc-pro (OSC camera) from my Bortle 3 backyard in the Northern Adirondacks, in Upstate New York.
Trifid Nebula (Messier 20/NGC 6514) is a star forming region. The most massive star in this region is HD164492A, which has a mass of more than 20 times the mass of our sun and is surrounded by a cluster of approximately 3100 young stars. It is approximately 5000 light years away from Earth. Trifid Nebula is approximately 42 light years across and has an apparent magnitude of +6.3.
Lagoon Nebula (Messier 8/NGC 6523) is an emission nebula and is a giant interstellar cloud of ionized gases. It is approximately 5000 light years away from Earth. Lagoon Nebula has a diameter of approximately 110 light years by 50 light years, and has an apparent magnitude of +6.
The two smaller images of Trifid and Lagoon Nebula were cropped from the wide field image. The wide field image was imaged with:
Celestron 9.25” EdgeHD
Starizona Hyperstar V4 f2.2
Celestron CGEM DX mount
ZWO ASI2600mc-pro Imaging Camera
ZWO ASI224mc Guide Camera
Svbony 60mm Guidescope
ZWO ASIair Pro for image acquisition and gear control.
Image Specs: 50 x 180 second exposures Gain 100
Camera sensor cooled to 0°C
No filters used as the ASI2600mc-pro has the built in IR cut window.
Calibrated (with darks, flats, dark flats) and stacked in APP
