Wide-field testing in the backyard - One of my tests from last night. This is 55 stacked 10 second exposures at ISO 3200 on the Sony A7s and the Irix 15mm f/2.4. (Stacked in Affinity Photo). The iOptron SkyGuider Pro has the camera locked on the stars and you can see the trees and transmission lines in the foreground flying by. That’s the rotation of the earth in the roughly 10 minutes I spent taking 55 exposures.
