- Calculate Image Scale and Field of View. This calculator may be used to calculate the image scale for a camera/scope combination. The total field of view of the camera is then derived using this image scale. Pixel Size: Enter the pixel size of the camera in microns. Focal length: Enter the optical focal length in millimeters. Width: Enter the ...

- Astrophotography - Calculator. The star trail method involves placing the camera onto a tripod and opening the shutter for an extended period of time. During the course of the exposure the Earth's rotation carries stars through the field of view causing them to trail on the film. The lens should be focused at infinity and the aperture set to ...

- Our calculator, at typical seeing of 2-4”, uses the Nyquist formula of 1/2 and the 1/3 to stop stars becoming square so the optimal range is between 0.67” and 2”. (0.67 = 2 / 3, 2 = 4 / 2). In summary, we are using Nyquist as a starting point, with a slight tweak, because we are typically sampling very small, circular, stars. Making it easy

- scale [“/px] = 206.3 * pixel size [um] / focal length [mm] When we consider imaging setup it is good to find out what factors are limiting our capabilities and to to fight them back. For low pixel resolution setups (3-4 and more arcsec/px) optics resolution limit is of low importance. In these cases the pixel scale itself is limiting factor.

- pixel size (microns) x 206.3 /focal length in mm = image scale in arcsec/pixel (3.9 x 206.3)/1200 = 0.67 arcsec/pixel If you are just starting out, this is difficult territory. Generally, anything below about 2 arcsec/pixel should be avoided by those starting out.
