Hidden in the outskirts of the Orion constellation, close to the Witchhead Nebula (IC 2118), we can find an area rich in interstellar gas and dust around the reflection nebula NGC 1788. This bright deep sky object attracts our attention among all that faint dust and gas. It is flanked by the dark nebula known as Lynds 1616.
I began imaging NGC 1788 on January 1st and continued on the nights of Jan 4th, 7th, 10th and 11th. I acquired a touch over 200 5 minute exposures. I remember it was bloody cold! This was imaged with the Skywatcher Esprit 120ED telescope at 840mm focal length using a ZWO ASI2600MC camera.
NGC 1788 is about 2,000 light years away from Earth and is sometimes called the “Cosmic Bat” nebula. It is made up of blue reflection regions, lots of dust, and a glowing area of hydrogen gas. It is close to the celestial equator, so it is sometimes visible from both hemispheres at certain times of the year. The brightest star in the nebula is 10th magnitude and is in the northwest sector.
Although this ghostly cloud is rather isolated from Orion’s bright stars, their powerful winds and light have a strong impact on the nebula, forging its shape and making it a home to a multitude of newborn stars.
I’ve enjoyed imaging these reflection nebula showing something a little different in our night sky.
Cheers!
