![]() ![]() ![]() You can then import it into SkySafari, to show the sky as it realistically appears from your location. You can create your own horizon panorama - for instance, an image of your own back yard, or your favorite observing site. Choosing any item from the list of horizon panoramas will automatically select this option! Creating Your Own Horizon Panorama The panorama is only displayed if you've selected Panoramic Image display option above. The currently-selected panorama is shown with a check mark. This section lists the horizon panoramas that are available in SkySafari. Please note: this feature is only available in SkySafari Plus and Pro. It's usually not worthwhile to observe objects below an altitude of 10 - 15 degrees, since they are lost in atmospheric haze. ![]() You can use this to quickly identify objects which - even though technically above zero degrees altitude - are still too low in the sky to be easily observed. Objects below the altitude you select will be considered below the horizon. Selecting this item leads to a slider that lets you set the horizon altitude used to compute rise/set times, and to draw the horizon line. Horizon Altitude: Lets you determine when objects rise and set above a specific altitude. When turned off, the horizon is always drawn against a clear sky background. Show Horizon Glow: When turned on, the horizon is drawn with a soft glow that increases with daylight to simulate atmospheric haze. When turned off, the sky background color is always black. Show Daylight: When turned on, the sky color changes with the cycle of day and night. Cardinal points label the north, east, south, and west directions on the horizon. Show Cardinal Points: Sets whether the cardinal points are displayed along the horizon line. You can select a specific panorama from the list in the section below. The horizon line itself is still visible.Īs Translucent Area: With a translucent horizon, objects below the horizon are visible, but so is the Earth.Īs Opaque Area: With an opaque horizon, no objects are visible below the horizon.Īs Panoramic Image: With a horizon panorama, the horizon is drawn as a realistic image that moves as you pan and zoom around the chart. When turned off, most of the other settings in this section are disabled.Īs Transparent with Line: With a transparent horizon, objects below the horizon are visible, as if the Earth were transparent. Show Horizon & Sky: Turns the local horizon and sky background display off or on. In SkySafari Plus and Pro, note that the horizon is not visible if you are not displaying the sky chart using horizon coordinates! Use horizon coordinates to show the horizon. Maybe we will see this in Corona 9, along with a fix for the problem with using Environment Overrides and Volume effect at the same time.The settings in this view let you control the display of the local horizon, and the sky background. So yeah, I agree that extra options for the Sky model would be great, but I'm not sure where I would begin with that. What I'm basically saying is that you can get the result you want, but usually through tweaking the Sky map. Lastly, you can feed it through a CoronaTonemapControl, so that it stays consistent while changing the Exposure. You can also ColorCorrect the CoronaSky map (for example give it a cooler temperature >6500K, to give it a unified blue tint), and maybe feed it to the Direct Override Slot, so that it does not interfere with the lighting of your scene. Oher times I have had success by increasing the altitude (not rarely at its Max limit of 15000m) and also changing the Intensity. Sometimes the horizon in real life is very close to what CoronaSky gives. In most cases I have been able to reproduce the reference I am after. I have been struggling with this as well, although in 3ds Max, but I would guess it's the same. ![]()
