First stack and post-processing on last night's Andromeda Galaxy (M31) capture. William Optics Gran Turismo 81 IV (480mm focal length, F/5.9) w/6AIII x0.8 flattener (total effective focal length with flattener is 384mm, F/4.7), Sky-Watcher EQ6-R Pro mount, Nikon D5100. Optolong L-Pro light pollution filter. 111 x 120 second lights (3 hours 42 minutes total integration), 30 darks, 30 bias. ISO 800. Stacked in Astro Pixel Processor, post processed in Abobe Photoshop Express and Paintshop Pro X7. Will probably play with the post-processing again to see if I can get more of the dust lanes showing without too much sky glow haziness. #astroimaging #astrophotography #astronomy #williamopticsgt81 #williamoptics #skywatcher #skyandtelescope #nightskyphotography #nikon #andromedagalaxy (at Westminster, Maryland) https://www.instagram.com/p/CHyY1FynCVM/?igshid=137xe16asn13y
