The Elephant's Trunk Nebula! Imaged last night from the back yard, I added nearly double the exposure time to last year's start on this target. The added exposure time brought out a lot more detail in the structures. Known for the similarity to an elephant lifting its head and curling its trunk, I have also been told it resembles the silhouette of a woman from behind, which I agree.
I created two color pallets for the image. The red colored image is true color and the blue/gold image separates the dominant gasses in the image, ionized hydrogen (gold) and oxygen (blue). I also created various crops and starless versions, each of which creates a different visual experience.
-Astro-Tech AT130EDT 130mm f/7 telescope with a 0.8x reducer, making it a 728mm focal length, f/5.6 scope.
-ZWO ASI2600MC Pro cooled camera
-ZWO EAF focuser
-iOptron HAE43 Strain Wave Gear mount
-Optolong L-Extreme dual narrowband filter
-Pegasus Astro Mini Powerbox
-Orion 60mm guide scope
-Orion Starshoot autoguider
-Controlled with a MeLE Qureduc4C mini PC running Windows
Software
-Sequence Generator Pro for acquisition
-PixInsight and Photoshop for image processing
-PHD2 guiding software
-173 x 180sec subexposures
-calibrated with 20 each darks, flats, and dark flats
-Total integration time of 8.7hrs
