HIGH ISO SENSITIVITIES:

Even with a slow shutter speed at very high aperture setting, the camera will still not get enough light to create a photograph. In order to brighten the photograph, a higher ISO sensitivity is required. Do not be afraid of using higher sensitivities.
When using f/2.8 lens at f/4.0 it will require much slower shutter speeds. The reason why we do not recommend using slower shutter speeds is because it will cause the star to leave streaks. Instead of using slower shutter speeds, simply increase the ISO sensitivity. FIGURE

SUGGESTED EXPOSURE SETTINGS:

Based on our experience, these suggested exposure settings may or may not help you to accomplish the result as desired. Give one or two of the exposure settings a try.
·         4s @ f/1.8, ISO 800 (with f/1.2 lens)
·         5s @ f/2.0, ISO 800 (with f/1.4 lens)
·         10s @ f/4.0, ISO 1600 (with f/1.8 lens)
·         10s @ f/2.8, ISO 800 (with f/2.0 lens)
·         10s @ f/4.0, ISO 1600 (with f/2.8 lens)
·         10s @ f/5.6, ISO 3200 (with f/4.0 lens)
If the photograph is underexposed, slightly lengthen the shutter speed or increase the ISO. If the photograph is overexposed, slightly shorten the shutter speed or decrease the ISO. Remember not to exceed 20s shutter speed and using much higher ISO will add more grain. 887

MENU SETTINGS:

We will now go in to the shooting and custom setting menu to make tweaks to some of the settings. If your camera does not support one or more features, simply ignore it. Watch this short video for settings

TRIPOD COMBINATION CHOICE:

A quality sturdy tripod legs a head combination is recommended Gitzo or Manfrotto brand tripod legs and heads for their steadiness. We do not recommend using a cheap and low quality tripod because they are not rigid enough to prevent the camera from wobbling the tripod as the shutter mirror raises or drops.
Unfortunately, even with a top of the line tripod legs and head combination, it does not hold the camera perfectly still when triggering. A heavy weight sandbag placed on the top of the camera and lens setup on the same axis with the tripod head is recommended to absorb the vibration that is caused by the camera’s shutter mirror, as it is being raised and dropped. By helping the camera stay still, it will dramatically improve overall sharpness. The sandbag must weight greater than the weight of camera and lens.
The ball head or geared (tilt/pan) head must have a weight capacity that is greater than the weight of camera and lens setup and sandbag.
