How to Calculate the Focal Length of an SCTLane
How do I use native APIs to calculate MD5? How do I use RSA to verify a signature? How do I encrypt a large file using SM4? How do I use the RSA public key (pk) to encrypt a piece of text? What should I do if AES decryption fails? How do I use the AES algorithm to...

There's a simple formula to calculate the correct shutter speed for any given lens, called the '500-rule'. In its simplest form, this is 500 divided by the focal length of your lens. For example, if you are using a 20mm lens, this would be 500 / 20mm = 25 seconds. This, however...
The field of view (based on focal length of the lens and sensor size) must also be known to calculate the size of the image footprint on the ground. Errors in altitude will also impact the accuracy of measurements made in the images e.g. lengths or areas of observed features. ...
If you know how much the lens has to move in and out then it's simple, after all my research, to calculate the optimum aperture. The formula to determine the optimum aperture, knowing the total image depth from the front to the back of the image is:...

How do we calculate magnification? 8x50 is 6magnification? And the view angle is generally 50degrees? I am asking on those generic scope finders who come with all basic telescopes like dobs for example. With a GSO and Skywatcher etc finders, the magnification is provided by the manufac...
