Hey all,
I was trying out astrophotography for the first time today. When I using the manual focus, I was using the focusing meter as well so I could zoom in. However, for some reason, there was so much flickering of red white and green, almost like noise. My ISO was all the way at 100, and there was still noise. I tried turning the aperture up to F.7, and it still didn't work. How do I focus if I can't exactly see the stars lol? Thanks!
P.S. These were the settings:
Camera: Sony a6700, 18-135
Shutter Speed: 10 Seconds
ISO: 100
Aperture: 2.8
Edit: here are some examples of the screen Photos of problem

Which camera?
You can try auto focus on some far street light or cellphone tower or brightest star then switch to manual focus so that it says locked. Try longest possible exposure, widest apperture and mid iso.
photos of the problem would GREATLY!!!! help
