WebJun 16, 2004 · If a 12” inch telescope has the ability to resolve approximately 0.4 arc seconds does this mean anything larger than 12” inches will show a brighter image but one is not likely to have seen conditions that will allow any finer detail to be seen. I know there are those of you out there who understand this far better than me so I await your thoughts. WebTo convert a degree measurement to a second of arc measurement, multiply the angle by the conversion ratio. Since one degree is equal to 3,600 seconds of arc, you can use this simple formula to convert: seconds of arc = degrees × 3,600 The angle in seconds of arc is equal to the degrees multiplied by 3,600.

Arcseconds Conversion Tool
Since antiquity, the arcminute and arcsecond have been used in astronomy: in the ecliptic coordinate system as latitude (β) and longitude (λ); in the horizon system as altitude (Alt) and azimuth (Az); and in the equatorial coordinate system as declination (δ). All are measured in degrees, arcminutes, and arcseconds. The principal exception is right ascension (RA) in equatorial coordinates, which is m… WebMar 6, 2024 · A second of arc, one sixtieth of this amount, is roughly 30 metres (98 feet). ... or approximately 0.36 inches at 100 yards; Human vision.
