Most of my past attempts for star trails at this location were unsuccessful because of the lighting in the area. The building and parking-lot lights always overexposed my images, and my older cameras lacked the flexibility in raw files to allow for a pleasing image after post-processing. The Sony a7rIII borrowed for this image has an excellent sensor that was more forgiving of my beginner abilities. There was significant post-processing using Photoshop and Lightroom Classic to colour correct the cast and let the observatory appear as white. The f/11 aperture allowed for very sharp trails and foreground details, but revealed sensor dust that is far too common in mirrorless cameras. Although I attempted to remove them in photoshop, the symmetrical star trails were not so forgiving to any manipulation, revealing the slightest adjustments./span
