## Pixel Scale in Astrophotography
Pixel scale tells you how much sky each pixel of your camera sensor covers.
### Formula
**pixel_scale = 206.265 * p / f**
- *p* = pixel size in micrometres
- *f* = focal length in mm
- 206.265 is the conversion factor from radians to arcseconds (with the mm/um unit adjustment)
A good rule of thumb is to match pixel scale to about half the typical seeing (e.g., 1 arcsec/px for 2-arcsecond seeing).

हल किया गया उदाहरण
3.75 um pixels on a 1000 mm telescope.
- scale = 206.265 * 3.75 / 1000
- scale = 773.5 / 1000
- scale = 0.7735 arcsec/px
