Video to show telescope resolution at different appertures.

This is a diagramatical video to show how bigger telescopes produce higher resolution images.
Please watch with the sound on - Verbal comentary. this video uses the refractor throuought. There are other considerations if you consider the obstructions in the open tube of reflectors. As a general rule, a refractor works as well (Both light grasp and resolution) as a reflector of 1.3x its size. 100mm achromatic refractor is equal to 130P Newtonian.)

In this video I have used smaller dots to represent dimmer stars. However - In the telescope the dots are all the same size. It's just the brightness that changes (This is difficult to accurately represent on a video as you have to make the dimmer stars grey... Doesn't look nice at all!).
