My first venture into deep sky photography with a dslr and basic tracker. Photographed at a farm just outside of town in a yellow/orange sky zone two weeks ago on a rare clear night with my Nikon D750 and 300mm F4 lens. Tracked with an IOptron Skytracker. 27x90 second light frames, 10 dark frames, 21 flat frames, 21 bias frames. Stacked in DSS and processed in Adobe Photoshop

As technical as efficient! Well done!
Possible to observe the spirals of M31.
It seems to be existing some noise with red pixels.
