I've always been curious how these photos work and how they stars revolve around one point. It's probably easier than I'm trying to make it.

Longer shutter speeds or multiple shots put together. Very easy to do with Photoshop.

I've done similar shots both ways. One with a 45 minute exposure and another with about few hundred shots taken over a few hours time. If you have a remote then you can accomplish both techniques.

You can also do a time lapse video if you have enough light.

To get the effect of the stars revolving around one point you simply need to get the north star in your image. They actually do appear to revolve around it.

You also need to live in a place where you can see stars at night. This has been my main issue...

I have the Rokinon, very difficult for me to focus during low light, but bumping up that f-stop in good light and going to almost infinity on the focus has given me some fairly decent results!

I'm confused. It's a manual focus lens...?? Just use your distance scale OR live view and zoom in, focus manually and then shoot .

*looks at location*

Even here in New Hampshire we have A LOT of light pollution so still need to be at least 30 minutes away for decent clear skies but long exposure, about two hours north away from civilization. Otherwise = orange glow.

This is the worlds most awesome selfie lens:

Love that Chilean one!

Fun lens! Shot this using my SL1 crop body.

I live in a typical suburban neighborhood with light pollution. Shot this 3 weeks ago when I bought the Rokinon HD8M-C (newer version w/removable hood).

7D, f/3.5, 20 seconds, ISO1600.
