AstroZoomLevel
✖
AstroZoomLevel
is an option of AstroGraphics and AstroStyling that specifies the level of resolution at which to render images.
Details

- AstroZoomLevel provides a base-2 logarithmic specification of map scale. An increase by 1 in astro zoom level corresponds to an increase in angular resolution by a factor of 2. An AstroZoomLevel value of 1 corresponds to data for the whole sky.
