How to Calculate the Focal Length of an SCTLane
5" is pretty close, the poles are only very slightly angled. Plus or minus the mirrors having different thickness. And the exact F.L. might differ from expectations due to the aperture being rounded to the nearest etc etc. The actual length to remove from the angled poles is even a tiny...

For this, a Barlow lens can be used in the eyepiece. It’s a diverging lens that spreads out rays of light for a clearer, more magnified image. How do you calculate the magnification of a telescope? To determine this, you’ll need the focal length (FL) of the eyepiece...
I have a fixed camera, but the objects are not stationary. The issue is that when I perform the calibration using a scale to detect objects with real measurements, if the height changes, I get different results due to pixel variation. My q...
The key to good photography is to create images with a strong focal point. This draws the viewer's eye into the picture and holds their attention. Here are our top tips for mastering focal point in photography.
To calculate the size of the sun's image in the frame of a DSLR with full-format (36 x 24 mm) sensor, divide the focal length of the lens in millimeters by 109. For example, a 500-mm lens will produce a solar image 4.6 mm across; a 2,000-mm lens will yield a solar disk 18....
