Lens test part 2

This time I went the other extreme. Rokinon 14mm f2.8 on Canon 60Da, Advanced VX mount, no counterweights just the CW shaft. A rough polar alignment and started shooting.
1st one the sky was just getting into heavy twilight
2nd one a little later.
3rd one later yet.
I cropped the last two to remove the strange clouds and lens flare from passing cars.
You can see Sirius, Orion, Tarus, Pleiades.

Really like #1 & #2. Third image seems to have quite a bit of noise.

I tend to agree. Thanks for the comment. I think my camera has a few hot pixels also.

Stacking a number of images can lower noise. Using darks can remove hot pixels.
Even without stacking, some SW can remove hot pixels -- Lightroom and DxO for example. But if you have two adjacent hot pixels, it won't remove those.
