A star tracker is not necessary for Milky Way Photography, but it will expand the number of options you have when it comes to camera settings. You are no longer limited by a maximum exposure time before you start to see movement in the stars. Once the tracker is polar aligned and balance...
As I stated earlier, there are five “visible” planets. These are thebrightest planetsin the night sky and ones that anybody can identify and photograph with a little guidance. There are eight planets in total (including Earth), but only five are visible to the naked eye. There areinner ...

The eye has two types of detector within the retina, the thin layer of cells that lines the back of the eyeball.These are called rods and cones. The rods are the low light detectors, whereas the cones allow full colour, high-resolution eyesight. ...
Visible light is light that can be perceived by the human eye. When you look at the visible light of the sun, it appears to be colorless, which we call white. It is made up of many color frequencies. The combination of every color in the visible spectrum produces a light that is colo...

Naming new stars and exoplanets With time-honored names now being settled for bright stars, completely new star names will most likely go toexoplanet systems. "Most exoworld stars are fainter than naked-eye visibility, so they haven't been named," Mamajek said. ...
However, Neptune and Uranus are not typically visible to the naked eye and will likely require a telescope or binoculars to see, she said. Here’s why there are suddenly so many planets visible in the night sky and how long you can look forward to seeing them. Ad Feedback How to spot ...
