Camera Orion by Derrick Lim - Astronomy Picture Of The Day - March 21st 2018

“This photo is a 4 panel panorama assembled in Astro-Pixel Processor. Each panel consists of 20X30s images for a total of 40 minutes of integration time. No calibration frame was used. The camera used was a modified Sony A7S and the lens was a Canon 85mm f1.8 stopped down to f4. The Star Adventurer mount was used to track the stars over the duration of the photo capture.
This photo was taken from Nakorn Ratchasima province, Thailand under Bortle 3 skies where some light pollution resulted in brightness variations in the sky. There was also a thin layer of high altitude clouds that resulted in the bloated stars you see in this image. APP’s light pollution removal tool helped to remove a good deal of the uneven lighting gradients, leaving a clean region in the image to do final touches on in Lightroom and Photoshop.
