[QUOTE="Devin-M, post: 6815952, member: 683547"] In this JWST image, the dimmer stars diffraction spikes (circled red) are the same length as the brighter star’s diffraction spikes, because both extend all the way to the edge of the image frame: [ATTACH type="full" alt="a_00001_0-2-copy-jpg.jpg"]316379[/ATTACH] With long enough integration time this will visibly & detectably be the case for every single star in the image, demonstrating the spikes are the same length but different brightness. These spikes are caused by edges and obstructions in the optical train, not the sensor or the star. See below, I used wires in front of the lens to create a 6 spike diffraction pattern. [/QUOTE]
