How to shoot tracks of stars

What we need:

1. Camera with working ISO 3200
2. Wide-angle lens with aperture 4 or more.
3. Strong tripod
4. Remote shutter
5. Patience, a lot of patience.

Training:
1. It is important to choose a point where the exposure is minimal – for this there are sites with exposure maps. For example – https://www.lightpollutionmap.info and https://www.artlook.us/service/wedding-cinematography-nyc/.
2. After all this, you need to track down the desired phase of the moon and the trajectory of its movement. To do this, you can use the application – http://photoephemeris.com Choose a new moon or stages when the moon is small, so as not to get light from the moon. If you need to highlight some object – choose the desired phase, the moon is a large reflector.
3. Then we act on luck – the weather. The most important parameter for us is cloud cover. Cloudiness is best viewed on resources oriented to astronomers. For example – https://clearoutside.com/
4. When all factors meet our requirements, we can move to the shooting location on the right day.

Shooting:
1. It is better to arrive at the shooting location a couple of hours before sunset to choose what we want to shoot.
2. We find an interesting object and see where we have the polar star – for this we can use the application on the phone, for example – http://vitotechnology.com/star-walk.html
3. Depending on how we want to build a frame, in other words, whether we want to get lines or circles around the polar star, we choose the angle.
4. We put the camera on a tripod (dark), build a future frame, focus, set the autofocus lever to M mode and don’t touch the focus ring until the end of the shooting. We connect the remote control.
5. We are waiting for astronomical twilight (we look at their time in the appendix from point 1 of preparation.) And another 20 minutes, to make sure that it is dark enough.
6. Making test shots, setting the correct exposure. For each frame, 30 seconds will be enough, open aperture and ISO according to the conditions. After that, we transfer the camera to continuous shooting and hold down (or program the smart remote control) the shutter button on the remote control. We need the camera to shoot one and a half to two hours. About a fully charged battery, I think it is not necessary to explain.
7. While the camera happily slams the mirror, we are trying to entertain ourselves – the main thing is that this entertainment does not give a flare in the frame, be careful.
8. After you have finished capturing the stars, close the lens cap and take a dark shot at the same settings. (While the matrix is ​​warm and may make noise)
9. Fun stomp home to warm up and solder hot tea.

Getting the finished image:
1. Option for the lazy program – https://markus-enzweiler.de/software/ (put all our files into it, separately select a dark frame and press the start button)
2. The second option is to collect in Photoshop, but I’m too lazy and I didn’t bother with this.
