Aperture – Large Now let’s dive into why we choose these particular astrophotography settings. In basic terms, aperture is the opening at the front of the lens that lets in light. The wider, or larger, the opening is, the more light can come through and hit the sensor. Wide aperture = shallow depth of field.The smaller the opening is, the less light comes through.īesides the amount of light it lets in, it also affects the depth of field of the image. That last part is very important to learn about, but for now we’ll talk about the light side of things.īecause you need to be shooting astrophotography when it is dark outside, there isn’t much light available for the sensor to read. So you need to help the camera get the most light available by making the aperture as wide open as possible. Great astrophotography lenses will be able to open up as wide as f/2.8, or even wider (f/1.8, f/1.4, etc). When you’re shooting at a wide aperture the depth of field is going to be very narrow. That means when you focus on the stars, the foreground will be a little bit blurry. Something to remember.Ī wide aperture allows you to let as much light as possible hit your sensor. After a successful reboot verify that the ports have changed to Ethernet mode.Shutter speed is how long the shutter on your camera remains open, which directly affects how long light is being registered on your sensor.

NOTE: You must reboot the switch for ports to transition into Ethernet mode. If you want to use, convert the stacking ports to Ethernet use the below commands. It will only remove the switch as a member of the stack.Ĭonsider we are removing member 2 from stack.ģ. This is not a command to renumber the unit. The command will not work if the switch is an active member. NOTE: This command removes the configuration that is associated with that member from the running configuration. Afterward power on the next switch one at a time until every switch is powered on. Power on the wanted primary switch first and wait until you can manage it.
