- It is calculated by taking 500 and dividing by your focal length. For example my telescope has a 1000mm focal length so for me: 500/1000 =0.5seconds. So I can only take a 1/2 second exposure before star trails …

- The reply I got from someone here on that was: Regarding f/10 vs f/20 for planets, I don't see the need for the Barlow. At f/10 your diffraction spot size is 80.025410sin (70530e-9/ (8*0.0254)) = 6.47um. The camera with the biggest pixels I know of has 5.8um pixels, so you'd already be oversampled without the Barlow.

- The negative lens on the right causes light to diverge as if it is coming from a virtual focus at B. The Barlow Lens, invented in the nineteenth century by the British mathematician and physicist Peter Barlow (1776-1862), is a negative (concave) lens fitting inside the focuser of a telescope. Unlike the better known positive (convex) lens a negative one does …
