Astro Photography with vintage lenses

Photos were taken with the Yashika 135mm F2.8 lens except for the Orion Nebula which was taken with the Pentax 70-210 @F11. All the vintage lenses I use are adapted to the Sony E mount for both my A6000 and A7R2. One of the incredible advantages of shooting with Sony mirrorless. All these photos are taken with my cameras and stacked in deep sky stacker software. The number of photos and lengths of each exposure varies depending on the camera, aperture, focal length and whether I was tracking or not. The star tracker I use is the Sky-Watcher Star Adventurer Pro Pack, but even a star tracker is not needed to get good photos of deep space objects. The Comet Neowise was taken with just the A6000 on a tripod after walking only a couple of blocks from my house. Proof you don't need to spend thousands of dollars to get amazing images of the universe
